I love love LOOOOOOOOVE Eclipse. I'm still on 1.1 because it has a fully functioning camera, and is stable, fast, and efficient as all hell. Customization on any Blur rom is limited, I would imagine because of framework subtleties and whatnot. Flick has a loooooot of potential, it seems like that dude is trying to make a super customizable blur rom. Haven't tried the newest version, but the previous one was sucking my battery like a vampire. As far as non Blur is concerned, I did a lot of bouncing around between Axiom Infektion, Full Throttle, and Koa, in order of preference, all AOKP, and if you're fixing for customizability and ULTIMATE battery life, those are the bros. Didn't really mess around with any CM9 roms much... tried Koa CM9 for like ten minutes... nothing horrible about it, I was just on a flashing kick. The problem with any of the nonblurs is that we top/HDMI doesn't work, and screen rotations and screenshots are subject to odd resolution changes.... amongst various other things. Kexec looks so super promising, but as far as I'm concerned, right now anyway, that is a whole different frontier, and it scares me. In short, Eclipse 1.1 is currently my fave, but really you just need to go on a flashing kick, download all of them you can, and try all of them. Because they are all awesome.
