Lol @ Jedi's test.
I would guess that if a load were testing by the same rider then it would come down to the type of terrain. For example, on a road climb the one with the lockout would win (or otherwise the one with the least active suspension such as single-pivots) whereas on a very rough rooty or rocky climb the one with the active suspension, such as horst-link Spesh Enduro, would work very well, provided the shock was set up properly (horst link bikes can wallow in their travel a bit if not set up properly), although that probably goes for all suspension bikes.
From my point of view, and as someone who went from a horst-link Titus Motolite to a VPP type Banshee Rune, that the best compromise is the VPP suspension that stiffens up under pedal pressure but is supple enough to achieve the grip required.
And then you have geometry, although I actually find my slacker Rune climbs better than my Titus, with the steeper HA, and despite having more travel.
I'm sure I have got some of this wrong and it is all IMO of course ;0)
