Tough call, but I will go with "Other" because for long (century plus) rides I'm also a big fan of the Assos shorts. This chamois gives me the fewest issues after a very long day in the saddle.
Coming in at a very close 2nd for me is the Castelli Truly Free. For whatever reason the compression panels in these just seem to keep the legs feeling fresh. In some ways I like this chamois better in that it is thinner but firmer, but I have to be a bit more liberal with the chamois butter to keep it comfy over a long ride whereas the Assos one doesn't seem to abrade my skin as much.
