Yeah, everyone is reporting excellent performance, but no matter what I did, I just couldn't get my phone to stop stuttering. There would be these really annoying lags that would effect everything, and keyboard performance was especially irritating. Not sure if it was a bad install, but if that were the case, then it must be a CWM recovery issue. I'm happy with the minimally modified AOSP though. Battery life is also excellent.
I had a similar issue with my TF101. I was thinking it was the fact that it was a sbk1 b7 revision because my B5 tf101 (which suffered a horrible accident) had no issues flashing anything. It turns out that the build for CWM was just buggy, so I switched to another recovery and magically ROMs started working without a hitch. CWM would screw up my mac address/bluetooth and it was incredibly frustrating.
