Got a link to that ROM? What are some of the differences? Like why would one want to use a ROM that has been ported to the 3D vs. the VM leak? Thanks in advance.

To be honest, I can't point out every little detail, however, I ran CleanROM ICS (the one with Sense and the one without), ViperROM ICS, and two of the MeanROM's prior to 1.7, and each had little things that just didn't jive with my particular phone. I recall clearly the MeanROM having touch screen glitches (bear in mind my digitizer is fine, does not glitch on any other ROM). Whether they've been corrected, I don't know.
However, the most recent version for Booster Shot has had no glitches for me. Only downside is my battery life has returned to what it was when I first got this phone. It's not great, but, I live with it because my phone doesn't glitch and everything works, including the 3D camera.
As for the difference between this and the VM leak? Not too sure other than this is what I understand: the port took a fully functional system from another phone and is tweaked and made to work on ours whereas the VM leak was a leak that devs took and developed the ROM around the bare bones of the leak.
