I've tried the Enduro SL and it rides great; its light (well under 30lbs), strong, and for the cost comes kitted with a decent spec list. I've tried a single pivot Orange Patriot and under braking I felt it didn't have the control of the 4 bar FSR on the Specialized.
You get used to that, a single pivot bike isn't as 'efficient' as a 4 bar when pedaling or braking etc. But it also has some advantages in other areas, climbing is one as when you climb on a single pivot bike it tends to tighten up the rear end and means that bobbing is reduced and platform damping (pro pedal) isnt required as much. I have an orange 5 and I went through various bike demos before settling on it. I couldn't stand the active feel of the other bikes, I preferred the more taught feel of a single pivot.
Its down to preference and what kind of terrain riding you'll be doing really though isn't it.
