Naruto & Fullmetal Alchemist: Brotherhood. (Never liked the original FMA, then again I am more a fan of the manga.)

Easily Love, Chunibyo and other Delusions. It's also the only series I've rewatched. A close second is Love Live! School Idol.

[Sin_mybb_import13631]

Hmm... I don't have a #1 but here are a few of my favorite;
Sword Art Online (ONLY arc 1)
Tasogare Otome x Amnesia (Dusk Maiden of Amnesia)
Akame Ga Kill!

[Ares_mybb_import14263]

Can't decide which one I love the most but my top 5 is:
Kuroko no basket
K-project
Hamatora The Animation
No Game No Life
Death Note

These are shared #1 since I can't decide which one is my fav

[Savage_mybb_import14314]

So many to choose from but it would come down to
Death Note
Zankyou no Terror
Attack on Titan
Code Geass
I enjoyed these amazing animes so much I've watched them more than once.

[Kevin_SF]

Tokyo ghoul hands down. There's no other anime as good as it.

[Queen]

One Piece and No Game No Life.

[Killua]

Can't choose between Naruto, Hunter x Hunter and Death Note.

[Hisoka]

Either Hunter X Hunter or Hellsing Ultimate. Probably Hellsing considering I have watched it around 6 times now.

[Pikami]

Death Note and Steins;Gate
