Another vote for the ZT 0566, both the reg. grip and the mini grip feels too fat / thick in hand, and Benchmades QC isn't quite up to par for the last few years.
Some would suggest the PM2, yes, the PM2 is very nice, but the tolerance is not there. Even when I cherry picked mine at the local B&M from the 3 PM2's left in stock, all three had uneven bevel grind (which I corrected soon after getting home), one of which can not spydie drop, the other has blade play. The one I picked was near perfect but had a somewhat loose retention as it had opened up in pocket even with the back against the seam.
My ZT 0566 came perfect, no play, perfect centreing, better blade steel, just need some time to break in. It can also be de-assisted. Very well worth the price IMO.
