I've been using Virtuous since I rooted my phone about 6 months ago. Now I'm using Warm Z 2.2 for about a week now and I absolutely love it!
Few minor issues:
1) The phone will reset when the screen is turned off and I get a pop up txt message through handcent. When I go to turn screen on the pop up txt is right there and I try to type or unlock the screen and its just frozen then it will eventually just reset.
2) A few other times when it just reset (think due to heavy load of GPS, WIFI, and possibly making a call at the same time).
3) Also when I was on a road trip w/ GPS, Wireless Tether, and playing music at the same time I noticed that the battery was slowly discharging even though I had it plugged into the AC adapter.
Overall, I am very happy w/ this ROM and hope the developer continues to work out some of these bugs as Sense 2.0 is awesome!! I don't see myself ever going to a ROM w/ out it again.
