Everyone has a different opinion. Make a good backup and flash til you find a good one. Run each for a day or two and see which on fits. I personally like the bamf team for roms on this bad boy.
First you have to ask yourself if you want plain ASOP ROM or you want a Sense ROM. I like chingy's Gingeritis 3D (Sense 3.0/3.5). I tried MIUI, meh. I think my phone runs better on Sense.
BAMF puts out excellent ROMs. Forever Cubed is a lot of fun, but I found Gingeritis to give better battery life and also a little smoother. Good luck, and remember to back up!
I do agree that Skyraider is a great modified stock sense Rom and thundershed is the best aosp. Bamf forever is the best sense 3 and infected is the best 3.5.
