I don't think the toe-strap on the Union's is as bad as everyone makes it out to be, but it is definitely not as nice as my Cartels. The ratchet is fine, maybe a little difficult to release, but it never jams up or anything.
+1 overall, I've had the best experience with the new Union toecap. Burton's is pretty tits, but I've had issues when it's dumping and snow gets in it, or the toebox of my boot is icy. Union's has a fucking deathgrip. The toeratchet is harder to release than any other ratchet but will release if you pull it just like any other toe ratchet. I also think it's not a bad thing since, if you're doing it right, you're spending more time riding and less time needing to adjust your bindings.
At Triple8...I've only owned one pair of Romes and (obviously) prefer Unions.
