Haven't tried either one of them, but I do have the Performance Forte Team MTB saddle which looks similar. I like it and it's really light. But your butt is different than mine. With these minimalist saddles, you must wear bike shorts or bike underwear with a decent chamois.
Good thing about Performance is if you don't like the saddle (or anything they sell), they will take it back. Kind of a pain since you probably don't have one you can drive to, but better than most other shops where you're stuck with Ebaying it for pennies.
One thing with any new saddle is you have to try it for at least 5-10 rides until your butt becomes accustomed to it. Also, if it feels uncomfortable, try tilting it forward or backward and see if that helps.
