... but, back on topic.
At this point, I can't say I have a "favorite" - so I didn't answer the poll. Compared to where we were just a few short months ago, they are all vastly improved. But I will say that the re-introduction of bugs - camera, gps, et cetera - in certain ROM series seems disconcerting; and moreover, when ROM releases become nothing more than exercises in applying themes, I start to lose interest quickly. (IMHO, that's what happened to Tazz v3 - v11).
I did just switch to CELB the other day (2.9), and as soon as I got it 100% configured, 3.0 was released, so I did an overlay install of that (but with a /data/dalvik-cache and manual /cache/dalvik-cache wipe) - something I usually try to avoid.
I did this mostly because the level of professionalism Conap displays in his posts - detailed changelogs; maintaining a github source tree; kernel development work; providing improvements and changes that other devs adopt; using a hosting site that publishes MD5 sigs ... the list goes on and on. I assume that if folks are careful in their release process, they probably also exercise the same care in their development process. (And similarly, if they are sloppy with their release notes, then ... well, you get the idea.)
If there is one thing which will make me go back to a 2.1 ROM, though, it is the "rild" segfault problem which seems to affect every Froyo or CM5/6 ROM. (This is the "call appears to drop, but it didn't" behavior). Drives me nuts; after all, the Eris is a phone first, and everything else afterward.
