6.1
may have a few bugs found when it is released, but in general what the beta-testers have found is very minor. The underlying base code is a refinement of 6.0x with a good number of requested features added.
If anything, unless something unusual pops up, 6.1 would be a better choice over 6.0x - better coding + less modifications to add in. I am looking forward to it being released here for sure.
