My top choice is no longer made. They're an '80s vintage pair of Terry shorts, and the chamois is just a layer of fleece. No one could possibly consider it "padding."
My next favorite chamois is the one in the Etxe Ondo Very shorts. They're not my absolute favorite shorts overall, but that chamois puts them near the top of my list.
Almost as good for me as that one - and a much nicer pair of shorts overall - is the one in the LG Neo Power shorts. It looks thick in the picture, but up against my parts it doesn't squish or insulate me from the saddle at all.
I've never found a pair of workout/running shorts with a gusset the right size and shape that the seams don't chafe on the bike. I'd be happy to wear something like Knott does if I could find a pair that works for me.
HTH. It's really an individual choice.
