Alaric is by far a way better character/Villian Love it!

Alaric is a better villain. Klaus is a joke.

I'll say the same thing I said in another pick about them:
I think that being a villain doesn't mean he can't be a complex character. I don't like Evilaric, he's evil-cause-evil, becasue Esther made him this way & you won't fine in his character any surprises, any deeper reasons or motives.
Klaus on the other way started as a big bad boring guy, but he was developed in very intersting direction. His devotion toward siblings, daddy issue, fear of loneliness, guilt of killing mother, interst in art,(a little bit forced,but still..) interest in Caroline... I really enjoyed watching him.
You can't expect anything like that from Esther's puppet, he'll be boring, scary guy messing with everything without logic or (even twisted own rules). I really, really can't wait to see him dead.

I have always liked Alaric , and it's nice to have a human on the show that can fight.
