Favorite ROMs for Galaxy Nexus?

I realize that this may be a repost, but I'm finally reaching the point where I can afford to buy a Verizon GNex, and plan on rooting it at some point (if not immediately).

Being that there are tons of ROMs out there, and I have absolutely NO knowledge around them, what are your favorites?

Please post a source link and why you like them, so I can get a further understanding of how each one is different.

Fire away!
