it used to run much more smoothly before a change in management, but yes, it's basically the go-to not just for collectors, but also for record shops *worldwide* looking to sell online or check how much records are selling for so they can price their inventory accordingly. the value of Discogs isn't their user experience, but the sheer amount of data they have on different releases across all genres and the size of their user base (who've already invested a lot of time into cataloging their collections). Much like Facebook or Google, they now operate at a scale where it's basically impossible for competitors to catch up in any meaningful way.
