I'm currently running Ice Cream Senseless. (Was on several variants of aosp ics but I got tired of the bugs and the camera issues). I've found it to be very stable and bloat-free. Of course as a Senseless rom it makes every attempt to be sense-free in appearance, which was appealing to me, but probably not what you're going for. As it's based on Ice Cream Sense, maybe that would be a good one to try if you want a more Sense-y UI.
Bettery life is very good, especially when using the latest Gingertiny kernel. With the kernel has come some random reboots for me, usually after about 30 hours uptime. I've had over 100 hours uptime with no issues whatsoever on the stock kernel, so I'm pretty sure the kernel is causing the reboots. Hopefully I can figure out a way around the reboots because I really like the better battery life and the ability to undervolt with Incredicontrol.
