IMO, this is the order of "Do-it-all" capability from what has been recommended.
GT (most AM)
Spec SJ FSR (I’d opt for the EVO model myself)
Giant Trance (most XCish)
I recommend a Head Tube Angle of between 67-68 degrees for a bike that can climb efficiently, but then rail the descents whether its butter or chunder.
Some other options out there:
Banshee Spitfire
Trek Slash
Kona Process/Tanuki/Kitsune (In order of most to least gravity oriented-ness)
Giant Reign 1 (not the X/SX model)
