Be aware that I've found a problem with some AVCHD footage in CS6 that didn't exist in CS5.5, namely that of long / spanned clips. Shorter (non spanned) clips don't appear to have a problem, and if that's what you are feeding in to CS6 then stay with AVCHD, there is no reason to transcode. Hopefully Adobe will fix the problem in the first update.
AVCHD clip spanning has been fixed in Premiere Pro Next. We were waiting for a fix from one of our partners who recently delivered it to us to include in the upcoming version.
I fully understand that there is a lot of frustration for those of you running Premiere Pro CS6 and looking for a fix to this problem. We definitely know about it. If you have not already done so, please create a feature request to fix AVCHD clip spanning issues in Premiere Pro CS6: http://www.adobe.com/go/wish. That will certainly help.
