And the price savings is nice, that's one thing about Surefire, they are pretty pricey. I don't think you'd regret buying either of those models, but that's a tough choice.
Another draw to Surefire for me was the "Warden" and the training suppressor they offer. I run brakes on my SBR's, partly to act as a "sacrificial baffle" and part because I almost always shoot the SBR's suppressed. When I shoot any of them unsuppressed, it's nice to throw on the Warden and tame the fire breathing muzzle brake a bit.
Whichever way you go, I definitely recommend investing in a set of suppressor alignment rods, while it is a low chance to happen, it is possible with QD's and a baffle strike on a personally owned suppressor will ruin a day real fast. I always do a quick check with the rods whenever I mount the can. While I've never tested it, I also love Surefire's warranty - YHM's is also probably pretty good, but on an investment like this, I do put some stock into the warranty.
IMO, both those models you suggested are great options.
