A hard question,

My list would include:
Gundam Seed
Gundam Wing
Knights of sidonia
Deathnote
and a 5th one is hard to come up with

I've seen so many it's hard to remember some of the specifics...


Akatsuki no Yona - For world and character development. It really deserved more seasons.

Outlaw Star - I wouldn't say it is amazing, but it was my first so I give it a special place.

Naruto - once you take the fillers out, it's a really good story.

Berserk - the original anime series

To Your Eternity - a more recent one, but I adore the character development. I felt the ending of the most recent season was a bit of a miss though.

1 - Bleach/Bleach 1000 Year Blood War
2 - Tenchi Universe
3 - Hellsing Ultimate

I don't watch them. But from the few I have, Pokeman and Naruto. Sasuke is smexy
