This is particularly sad because the Galaxy Nexus is a brilliant phone running stock Android. I've found the stock Android ICS experience to be much better than what you can find with a version of Android modified by the vendor (at least for the other phones I've seen). I'm pretty sure it's one of the best options for Android phones, period.
What other options have you tried? My experience with stock ICS (AOSP based ROMs) are terrible, the GUI is unintuitive, simplistic to the point of being ugly and rather limited in functionality as opposed to older versions of MIUI (not based on ICS). Sense is not only ugly, but slow too, I have not tried touchwiz to comment on that.
