Ok, So I ordered a bunch to test from Amazon.
KNIPEX - 45 10 170. These ones are the nicest feeling of the bunch. They have a much smaller cross hatching on the tips then the rest. So for thinner rings they work really well. The tip thickness is about the same as the Photo / Wilde so no advantage for confined places.
KNIPEX Tools - Special Pliers, Retaining Rings, 30 Degree Angled (4521200). I was not a fan of these and was planing to return them. However they have the thinest cross section of the tips and I can across a few round wire snap rings today where these where the only option to remove them.
The tips dont have the cross hatching, so they only work on rings where the ends have been angled. They won't grab rings with squared off ends at all. Plus they do not want to fully close without a lot of additional force. The joint is no where near a smooth as typical Knipex quality.
Stanley Proto J250G Proto 9-Inch Lock Ring Horseshoe Washer Pliers. I think these are the best of the bunch. They have both the cross hatching and the recess in the tips, so work well with all snap rings. The tips are the same size as the black Knipex, but these have larger and longer handles so they have more leverage. I do think the black Knipex feel the best in the hand, but on 2-3" diameter rings, these are superior in every way. These are made by Wilde, and are the same as the Snapon ones as well. With the PROTO badging, they are cheapest. The Snapon ones I borrowed are a bit more polished, but otherwise same exact tool for 3X the cost!
Wilde Tool G705.B/CS 10" Compound Lock Ring Pliers-Black Oxide. These ones are a hard no for me. They dont have the cross hatching on the tips, so only work with rings that have the angled ends and not the squared ones. Plus these ones are quite a bit thinner in the cross section, so want to deflect a lot.... same problem I had with the Craftsman ones. Plus these tips are super thick, so not great for confined spaces. Even with the compound action and the longer handle, they didn't give me any mechanical advantage over the Proto pliers due to the tips deflecting.
