I'm trying to decide between Turner/GAS and another option which claims it has more than 2.5x the impact & load bearing area... but I'm skeptical...

The Turner part is made by knurling a 2.726" diameter. The knurl crests produce a larger diameter than that. Unfortunately I don't have a record of the crest diameter when new.
For your info, the crests on my worn out part measure 2.742" diameter. Looking at the worn crests it is apparent that they represent only about 50% of the bearing area. It is not unreasonable to assume that when new they only provided 40% (= 100% / 2.5) of the available bearing area, although I would guess even less.
The diameter of the part I made to replace it is 2.758", with 100% bearing surface.
