I've been using Deezer for almost a year, and if want to use it as a music discovery tool you're in for a bad time (this is what I found Spotify actually good at until around 2023). It's also really bad if you listen to artists whose name clashes with others. They do have a reporting system for this, but it takes a loooong time to see any changes. Quality is pretty decent though, although sometimes the apps (desktop, phone AND browser) will just stop playing songs randomly and error out.
