I tried out 2.2.10. Honestly it was fairly slow for me. I also was getting very annoyed with titanium backup and how i was unable to cancel anything. I accidentally started doing a backup instead of restore, so i closed it out and it was still going in the background, and i even stopped titanium, it still continued.
Once ICS is better optimized for speed, and not so choppy between menus, i will give it another try, but for now im staying with my GB version.
But then again, the Droid Inc is still my only phone, and its still fairly old and wont run as well as newer phones. So that probably have a great deal to do with the slowness.
