Worth noting that it's the Spectral that has the slacker head angle (67, compared to 69.5 for the Nerve). The Nerve is aimed more at the XC market while the Spectral is more enduro style (slacker angles, more travel, beefed-up brakes, dropper posts).
I've owned the Nerve 8.0 for just over a year and think it's fantastic for XC and trail centres (Coed-y-Brenin, Penmachno, Llandegla, Dalby, Hamsterley). Very light, very fast. Having said that, the Spectral wasn't released when I was buying, if it had been then I think I'd probably have gone for a Spectral! Maybe also worth considering the 27.5 wheel size.
All my experiences with buying from Canyon have been good. I subsequently bought a road bike from them as well (Roadlite 6.0), again I'm very happy with the quality / spec / ride.
