Is the 6800 w/new ROM better than 6700 w/new ROM? see specific questions.

I'm considering buying the sprint mogul. I currently have the 6700 which I keep updated with the lastest kitchen (WM6.1). All of the comparisons I've found by searching are from when the 6800 first came out. I'm looking for your thoughts on a 6800 with the latest kitchen and how that compares against the 6700.

I'm wondering if some of the earlier complaints of the 6800 have been fixed by newer ROMs. Some early complaints I heard are:
6800 is slower than 6700
6800 bluetooth is very buggy
6800 volume on today screen can't be controlled by wheel 6800 tethering usage can be detected by Sprint where it could not be on the 6700

The reasons I want to upgrade are:
smaller form factor
built in GPS

I'm assuming that since the 6800 has more ROM, I can cook a lot more into the kitchen. Correct?
