I think it's a flex + alignment thing. If you've got a frame that doesn't side load the shock, and the alignment is bang-on, they're fine. The trunnion bearings on my Carbon Patrol last forever with an annual repack.
But get a bit of twisting or alignment that binds even a little bit, and you're in for some frustration. My shop/shock buddies have seen quite a few prematurely worn trunnion shocks and destroyed bearings.
Basically there's a lot less margin for alignment error or weird loads with trunnion vs the standard mounts.
