I like BM Fab.
To me they are all stronger and you hope they break correctly before something else breaks but there really is no saying which bumper will for sure do that without any evidence.
One thing to keep in mind, if you get stuck a lot, or pull on the bumper often, make sure you get something that doesn't cut into your fingers especially when it might be awkward to grab. BM Fab is good for this but the skinz one doesn't look as comfortable to grab. I would also look into Backwoods BMP.
Another plus to the BM Fab bumper is I think you can get it to work with the Ski-doo extreme skid plate with a little finesse
