As an immunologist I absolutely love the book Immune by Philip Dettmer (the guy behind kurzgesagt)

I didn't use deezer that long but found the ux a bit confusing (maybe because I got used to Spotify). Had no problem with the qobuz ux.

I switched from Spotify to tidal then deezer and finally landed on qobuz. While the app still has some problems and the music selection is not as massive as on Spotify (but mainly in super niche content), the higher artist pay and amazing soundquality are definitely worth it

Tip? You mean the protective pieptte-hat? (And yes, I've had med students call them that and trying to pipette without a tip)
