The 951XC is a re-painted Sniper T with a rhythm fork and NX build for $2500
The 951 Trail is a re-painted Primer with a rhythm fork and NX build for $2600.
I had a Trail last season and got along with it OK. I liked the TRP Slate T4, and the NX group worked fine for me. Wanted to upgrade the wheelset, wasn't in love with the 36 rhythm, and could have used a touch steeper seat tube, but overall it worked for me. Cracked the top-tube though, from forum posts elsewhere it seems like the top tube might be a little fragile--otherwise I'd still be riding it.
For $2500 I'm kinda considering the XC for my wife to get her on a full suspension. Build kit compares pretty favorably to the YT Izzo Core 2 for $3300 although seat angle is way slacker and I kind of worry about the standover and dropper insertion since my wife has short legs and long torso (Izzo standover is 5.4CM lower)
