I've got a rose Granite Chief (150mm) - bought it 4 years ago (?) and have been really happy with it.
As a do-it-all bike it's been great - as burly as f*ck, but damn light too. It was the "2" so came with a full X9 drivetrain, Revs, RP23, DT swiss wheels (inc star-ratchet hubs), Elixir CRs and nobby nics at both ends. All for about 1,500 quid.
Their UK rep (Fin) met me and a couple of mates at Swinley so I could demo it. Really nice chap - came riding with us for a couple of hours and was able to make sure I got the best size, and gave me some tips re: spec (that you can play with on the configurator). I've added a reverb and swapped the stem/bars, but otherwise its running stock.
The Canyon nerve hadn't really "landed" at that point - but my friend bought the nerve AM a few weeks later. Both bikes are great, but the rose is noticeably better put together I think. The roses are assembled in Germany (there is a vid online somewhere) and it showed - everything was dialled-in straight out of the box, whereas the Canyon was mis-shifting, brakes needed bleeding etc etc within a few rides. Dunno if that's a concern for you - depends if you are a tinkerer or not.
Also: At the point I bought the rose, I had broken an Iron Horse and a Tomac frame - so I was on the lookout for something with a decent warranty. The rose comes with a 10 year warranty against the frame breaking.
Downsides: It took ages to arrive (5 weeks?), and the press-fit bottom bracket is annoying, but otherwise, that's it.
Since I bought it, the specs have changed a couple of times - magura and race-face bits and pieces are appearing, and the monarch seems to come on the lower end models now. If I was buying again I would be looking at the YTs and the Canyons also
Sorry, ^ quite a lot of waffle!
