CachyOS actually grew a lot through 2025.
They reported: Discord: 20,500 members (+355.6%) Reddit: 30,000 members (+867.7%) Forum: 8,500 members (+466.7%)
And that "ISO downloads reached a peak of 133.000 per month and a total of 847.000". Pretty impressive.
I am in a similar situation as the one you're asking here and I have sadly found Qobuz's selection too lacking in practice for me to use it which is a real shame because there's a lot to like about it. For example, attempting to import my favourite songs playlist from Spotify or Apple Music to Qobuz resulted in only ~60% being carried over. The majority of my missing songs were from a large variety of japanese artists or very niche genres like beatboxing, so I think most people would find their selection perfectly fine.
To me it's alright solely because of Heroic Games Launcher that covers the Epic Store and GOG. I must admit I rarely end up playing the games from Epic, but they do give away some really good games from time to time. To be clear, I would probably never actually buy anything from Epic for a few different reasons, but getting free games is cool.
