Replying to Mountain Bikes

Alright, so Alta closes next week and I'm finally upgrading my '12 specialized enduro. I love that bike but it's beat to shit. I wouldn't dare make this thread on pinkbike. I'm a major biking Jerry (what's a Jerry in biking terms)? Anywho, I'm gonna buy used but I want to be a smart buyer. Some standouts are another enduro, SB6, reign, nomad, range or spartan. Anybody have personal experience with any of those? Are there any that I should avoid or some that pedal better than others?
Thanks
