I have no experience with the Bontragers so I can't comment on those.
Just to be difficult, I'm going to suggest a couple other options you didn't mention. On my commuter bike I went through about three sets of SKS fenders in three years. They all failed where the rear fender attaches to the seatstay bridge, but each in slightly different ways. Then I tried Planet Bike Cascadias and they're still going strong after three years.
For my brevet bike I like aluminum fenders. They offer better coverage, they hold up very well and they look shnazzy. I've had great luck with the Velo Orange aluminum fenders. They're a little more work to install, but once on, they're more like a permanent part of the bike than any plastic fenders.
