I'm going to be forced to be brief here in an attempt to answer the questions without using spoilers.
Best Anime #1: Fate Zero
Why: It deliever's in every department. Animation, voicing acting (Sub), writing, character development, story. It's my default anime to suggest people when they ask to get introduced to it because it helps start them off with a bang.
Best Character in Show: Tricky, but I would have to say Kiritsugu.
Why: Out of every character in the show he's the one to use his brain the most and pulls off being someone the audience can emphasize with while still simultaneously doing pretty bad stuff but also not being a bad guy. Though Iskander (Rider) & Artoria (Saber) are both outright amazing as well. Well, most of the cast is but I can't make every other character 2nd place.
Worst Character in Show: Emiya. (Does that count? He technically appears in Fate Zero. If not then Kayneth Archiblad El-Melloi)
Why: Emiya more just makes a cameo in Zero, but in Fate Stay/Night he's the total opposite of Kiritsugu. Being very predictable, and always following the "I'm a hero!" ideal even if doing so is completely suicidal. Even that doesn't count though, then Kayneth (who is still a good character) because he's overly arrogant. He relies on the fact that he's a Mage to hand him victory on a silver platter, despite the fact there are other mages involved who are taking things very seriously.
Love the Ending, yes or no?
Dramatic Face-Off's between the remaining Servants and Masters? Surprise ending (if you don't watch Stay/Night first) with proper Arc developments for most of the characters simultaneously? I don't think much better endings can be executed.
Best Anime #2: Clannad - After Story*
Why: The Feels!
Best Character in Show: Tomoyo if you're looking for a more serious character, Fuko if you want
silly stuff (warning this link is a mini-spoiler). *IF* we're going all of Clannad, since After Story is technically an expansion/later season of the show. If we're kept to just Afterstory though, I had to default of Tomoya (No I didn't typo Tomoyo).
Why: Tomoyo because every scene has her doing something bad ass without making it look like it's trying too hard, while also being a very calm and collected character. Fuko because every scene is just filled with comedy gold. Tomoya because he's the one After Story follows almost exclusively, so there really isn't any other options.
Worst Character in Show: This may be Blasphemy to Clannad fans, but Nagisa.
Why: Her routine just get's rather repetitive after a point, likes Dango's, get's shy, follows lead. Like's Dango's, get's shy, follows lead. She doesn't really ever grow much other than once in the while speaking up to someone. She was a solid character, but unlike others I just didn't see much development or growth so while I was invested where others were going I kind of left her to the side cause I knew it was going to be the same thing.
Love the Ending, yes or no?
The End-Ending was a bit of a "Happily ever after" cop-out (though to be fair, they build it up since Episode 1 of Clannad). But the majority of the Ending got across exactly what makes the Anime so well known, it takes all the time you spent being invested in the characters and then uses all of that investment to hit you with feels so hard that Veterans who claim not to cry in war have claimed to cry at this ending (Granted, claimed through YouTube comments).
*You NEED to see Clannad first for After Story to have much effect on you, and Clannad itself is what I'd rate a decent anime but nothing phenomenal.
Best Anime #3: Log Horizon
Why: A premise I outright love from being a Gamer, being trapped in an MMO and having to find a way out. But they execute on how such an MMO would work in such a scenario in a very creative manner, and know the perfect blend of serious moments and silly moments. As well as knowing when to still make the silly bits important and not have it be filler.
Best Character in Show: Shiroe.
Why: He's the brains of almost everything complicated in the show, may it be MMO battle tactics, how to do a proper Raid, how to manipulate the MMO's economic system for player growth, the diplomatic relations between players and NPC's etc.
Worst Character in Show: Nureha
Why: Admittedly we haven't seen much of her yet. But what was shown so far basically seems to make her some kind of furry who lacks self-respect and is utterly dependent on Shiroe (someone she hasn't really seen for years save for one case). Not really anything to get invested in yet.
Love the Ending, yes or no?
The Ending of Season 2 was ok, but it wasn't the ending of the Anime as they're still making Season 3 to my knowledge.
Worst Anime #1: Sword Art Online
Why: Imagine Log Horizon, rip of all the creativity and complexity of how such a world works, and replace it with poor fan-fiction quality writing. Which shows the most in the anime's romance, all the fan service scenes & shots in season 2, complete jumps in logic at certain key situations (one get's them out of the MMO, another involving finding a kids parents) and a main character who lack anything to actually show he's a good person so the writers make sure everyone keeps calling him good in an attempt to make the audience believe it.
Best Character in Show: Kayaba Akihiko
Why: As the main and elusive villain may have been blessed with limited Screen time. But he was the only character that I found could be taken seriously and actually seemed to be putting much thought behind his actions, even if he made some mistakes.
Worst Character in Show: Nobuyuki Sugou
Why: The Villain to fellow Kayaba, he was in blunt terms a murderous child molestor who had a huge power complex over control of an MMO, and had zero redeeming qualities.
Love the Ending, yes or no?
Season 1 used a complete jump in logic to bring you the ending out of the blue without warning (unless if you're streaming and tracking the episode numbers) as well as a cop-out for the main characters to cover their idiotic reactions. Season 2 felt like how a poor fan-fiction and/or forum RP would end between two teenagers who just learned the concept of sex and using rapists as characters.
Worst Anime #2: Garzey's Wing
Why: Huh? What is this now? Anime Poor Writing and Rushed Plot? Dear God! I am running from Army of shit anime now! These people have no personality, it is suck! (Yes, the writing is like that. If not worse).
Best Character in Show: (Is it bad I can't even find a reference page to connect faces to names?). Basically the starting villain egyptian looking dude.
Why: For no reason than he get's off his horse by flipping it over. The animation for it is awful, silly, and hilarious. XD
Worst Character in Show: The Main Character
Why: Because all the characters are painful to listen to, but at least their lines are usually limited so you got variety. This guy is consistent.
Love the Ending, yes or no?
Yes, when it ended.
