What I love from Bandcamp are the recommendations. Generally, when you are suscribed to a band mailing list, sometimes they are mentioned on a Bandcamp article where they recommend similar stuff. I definitely found more stuff from it compared to years of using Spotify.

Although you need to purchase stuff and there is a limit to listen, you can download your purchases and even find cool merch. Plus, as @nromdotcom@lemmy.ml said, Bandcamp Fridays are a huge support to the bands.
