I was rooted, used CM and BB, loved both of them, and overclocking. Now on my second Droid, the first is about to go back for data corruption problems on the first and replacement SD cards. (yes I put it back to stock before shipping).
I am so close to rooting this second phone, but it's so snappy and fast with Launcher Pro and ADW. I hardly notice the difference between this and the
1 ghz root from before. Maybe web pages load a microsecond slower, but I don't miss the "acore" fc's and the other odds and ends errors that would pop up. OK try a different kernal, get stuck at the M, nandroid back, etc. etc. All lots of fun for a techie.... Bugless was great but never really bugless for me, and I may miss the miscellaneous tweaks available in both BB and CM, but I like having a VERY STABLE phone. When I start reading about the changes Froyo brings I'll probably re-root then, or maybe just wait for the OTA.....
