I agree. If you haven't tried CyanogenMod 6.1 RC4, I recommend it. I just flashed it a few days ago and I'm really happy with it. Most of what I liked about UD 2 was essentially taken directly from CM. The level of customizability in the ROM settings is insane, way beyond what most would need but always nice to have more control over your device even if you decide keep the default settings.
Besides a higher level of customization, the main difference between UD & CM is aesthetic, but CM can easily be customized to appear virtually identical to UD.
After using UD I've never been able to deal with a ROM with a white notification bar, it's has to be either black or transparent. This link provides an update to give the newest version of CM 6.1 (Release Candidate 4) a black bar:

I then flashed a fonts pack that is similar to the UD fonts, and I then had a ROM that aesthetically looked almost identical to UD but to my tastes has an edge over UD when it comes to function and performance. More things seem to "work".
