I come from a running background and running shoes can vary in price and quality. I never felt like I needed the super expensive shoes at $200 but the middle of the road shoes from $130 to $150 were all the same as far as quality. The question was what fit me better. Same with bib shorts. Find what works for you and stick with it. Nothing worse than trying a new chamois and finding half way into a 80 mile ride that it chafes.
I’m not bib shaming anyone. If the lower end bibs work for you, then go for it but it’s certainly been my experience that the middle of the road ones fit better for me and definitely last longer.
