We have a pair of the magnesium mil-surp ones, a pair of 25" MSR's (I forget the variant), a pair of 36x10 cabela's Alaskan (I'm pretty sure are tubbs), and a set of mini ones for kiddo. MSR's are nice when there's a good crust but not enough to run it in plain boots - they're quite underwhelming in just about everything else, even with the tails that make them 32". The 36" cabela's are good for lighter snow, but powder will still make you work hard - they're difficult to back up with, turning is easier than the mil-surp's and much harder than the MSR's. Mil-surps are actually pretty decent on lighter snow as long as it's not bottomless fluff, but backing up is potentially dangerous and turning is best handled by walking in an arc.
The rubber strap bindings are annoying on every single pair we have with them. The cotton or whatever it is bindings on the mil-surps are surprisingly easy to mount/dismount once you get them set right. If you have a bench or some hard pack to work on, it's not a big deal, but if you're trying to put them on while clinging to your trucks bumper - PITA!
