I went through a very similar process last fall. And i analyed the crap out of the bikes on my short list. I knew every angle, legnth, spec. I had a chart comparing all of them. I was neurotic about the decision. I Demo'd a range 2 on Seymour. Climbed really well, very light, but felt the bumps going down. It was a medium and I am just under 6'. I bought a Slayer the next week. I got the large due to the straight up geo. I only got a few rides in before it got stolen. The slayer was a good bike, climbed well, descended well, and was still pretty light. I didn't get a chance to really push it though. Ironically, I was to take the slayer into DB in N Van to get the fork spring swapped out for something stiffer. I was bottoming on my local trail, randy's. When the dust settled from insurance claims, etc. I ended up with a Reign X2. Like others have said, you give up a bit in the climb to get a bit on the down with the Reign X. Which for me, suits my riding more. At the end of the day, its hard to beat the feel of a coil shock IMO. But if bike parks weren't an option for me, I would look at the range in a heartbeat. any one of those bikes are solid. And after all the time I spent researching and going to stores to look at them, I don't think it would have mattered that much what I ended up with. They are all great bikes. And after you get used to the bike you do choose, you make it work and it's awesome.
Good luck.
