I can't speak to the SJ, but I'm really impressed with my Enduro 29er...I was in the market for a bike that could pull double duty between "light" lift days, as well as trail work. I figured I'd probably get an XC hardtail for shorter rides or for more XC work. The enduro, however, is way better than that. For reference, my previous bike was a 650b converted Cannondale Rush.
The fit is shockingly perfect. I don't know if you like the whole short stem thing, but it's exceptional with a 50mm stem and flat bars. I'm 5'11" and ride a large, FWIW. It's a BIG bike, but it doesn't ride like it. The wheelbase is huge, it's tall, and the wheels are big, but on trail, even on twisty stuff, it handles like a way smaller bike. It never feels out of place or disconnected. Spec really nailed the geometry on this bike.
The climbing and pedaling is also really, really good. I have the comp model, which has the front derailleur. In the 22, it's a great technical climber. It bites into the dirt and scoots forward just like you would want it to. If you're still in the 22 on the trail, you won't notice it. It's not excessively "anti-squatty", but when you're laying down torque it will bob. In the 33t, it's a little more mushy, but that's not a surprise. Don't stand and climb in the 33. It'll be perfect for derping around highland, as there's no feedback, and I won't be racing. I think the bike would be great with a 28t single ring in front.
I don't have much time on the bike yet, but the first ride has got me wondering if I should bother with a second bike, or just spend some money on a better shock and some extralight wheels for trail duty. Then I'd have one set for burly days, and another for XC days, they're be easily swappable, and shave some weight.
tl;dr the e29 is really, really impressive.
