Ok, here are my votes:

Best Battle: Conflux by Superjazz.
I've been around for 11 years now (under different names), so i've seen a lot of awesome lvls and know most of the special tricks and gimmicks there are. However, sometimes I still see a design that wows me. This was one of these cases. GJ.

Best CTF: Dusk of Serenity by Ragnarok
Great eyecandy, layout worked fine. I downloaded this after some of the aEs members asked me to add this to our server. We then proceeded to play this, and although I got pwned as usuall I really enjoyed this lvl

Best Other: the Citadel Test by Lithium
Fun test, portal references, not too hard (even for me XD)

Best 2011 pack: BUT ENOUGH TALK (OLC)
Great line up, plays well.

Best Singleplayer: Neutral (I dont vote here)
Haven't played much SP since 2006 XD

Best Tileset: Rage of Aquarius by Violet CLM
Looks good

Best JCS'er: Ragnarok
From the ones listed, his stuff rocks the most (this was hard...)
