Thickness ≠ comfort. Just like with saddles, many people equate thickness and softness with long-term comfort.
To contribute to the discussion, I have bought a pair of DHB bib shorts for about the same amount and the chamois is atrociously bad. Basically, I wanted to see whether they were good enough for indoor rides and they are not. I have also a pair of mid-level DHB shorts, and they look really, really old even though I bought them 3 years ago or so. The chamois has gotten a lot less comfortable, so trainer rides over 1 hour sometimes get uncomfortable.
