I own a couple of Leshiy 2's and an SK-19. I have owned a Steyr Pro-X. The L2 is the semi for me. Solid, reliable, just works. I don't understand the hate for the SK-19 trigger (it's different, not bad) but it's still not the rock-solid performer that the Leshiy 2 is. Where the SK-19 is kind of a fussy gun - one I'd recommend only to "advanced"* shooters, the L2 is an easy going reliable every day shooter.
I haven't yet had the pleasure of playing with a Huben. I'm waiting for things to shake out a bit before I bite. Sounds like there are some issues to work out, if, perhaps, only in quality control.

* "Advanced", in this case meaning someone who is ready, able, and willing to disassemble a relatively complex gun and replace o-rings, perhaps on a semi-regular basis.
