(WARNING! The following is my opinion only!)
If your phone is your lifeline, and you HAVE to have it be as solid as possible with no glitches whatsoever, you have no choice but to run either 100% unrooted stock, or something like Mr X's stock rooted ROM
All other ICS builds are hacks (some very good ones, but hacks nonetheless).
ICS official will be released in the next couple of weeks for our phone and I would suggest be patient.
