Apex is the best ROM out there right now.
I've tried Liberty, but had too many bugs (lockups requiring battery pulls, and bluetooth audio routing not working).
I SBF'd back to .320 and ran Maderstcok to get me back to .340, put Apex on, everything works the way it is supposed to, I can use the better parts of Blur (gallery, camera, Corp Sync) without having to use the worse parts (the launcher, and social networking junk).
Darkslide is nearly as good as Apex (if you like everything colored black and/or dark gray). Some items in Darkslide are black text on a black background (reply option in gmail being the first one I noticed).
