Not a lot of difference, and basically an overdrive.

Other notable differences are that 5-speed has a TSB for the shift forks that should (must) be performed and I think Neil covered that in his diy.

A negative of owning the 6-speed (non-m) is a serious lack of available aftermarket flywheel/clutch combinations by comparison to the 5-speed. The clutch discs are both 240mm but the input shaft splines are much different.
In theory any z4m clutch should work. Don't quote me on that though
