[Closed] Giant Trance X2 or Canyon Nerve XC

Sooooooo if it was your cash where would you put it???
Also I know I need to throw my leg over a Trance as I hear the sizing is a bit peculiar. I am 5'8" (give or take) and a medium is the suggested size but at 18.5" that sounds a smidge large to me. How do they fair??
Also is the BB really that low??
I am swinging more to the Giant due to after sales and the soft fluffy feeling knowing more about the brand.
Anyone got any more real life gen as opposed to magazine BS (Bike Radar's web reviews are laughable)on the Trance or Nerve??
Cheers
