He assumed that some of us feel one was better than another, when in fact that was not the case. He also assumed that one part was inferior, or, fragile over another, which as far as I am concerned, is also not the case.
I have 3 of the S mounts, and aside from human error on my end, they've worked with no major issues. Ive also worked with the mount he has as well, but since I use the ft16 receiver, ive never had the types of issues he has. On the brief times Ive used the yn622s' it was with the sync cable and was secured to the 360 with a rubber band. Heck I didnt even know they could trigger the 360 from the hotshoe. Things one learns...
Point is, one is not really better than the other as far as I am concerned, they do well for their situations, and either one is superior to a lot of the other options on the market.
