I have a pair of Union Force DLX's. They are nice, light, and super responsive. I first had them on my board I ride at the resorts, then when the area closed I swapped them out to my splitboard. They were what I was using on Dead Dog Couloir past weekend. Surprisingly comfortable, great ratchets, overall a top notch binder. I've demo'd Union bindings the past 3 seasons and they have always come out as a top 3 binder that I demo.
I was previously using last years Salomon Relay XLT's on my Splitboard. I can say that the Unions are far superior from a performance and durability standpoint. About the only thing I can say about my force binders is that they are not really a freestyle binding that I can tell. More of a freeride, great to do gnarly lines with binder. Then again, I am just not into freestyle anymore, so I am probably not the best judge of that aspect of riding anyway.
