Mullvad is looking pretty good. You can even sign up for them through FirefoxVPN and then you’re also supporting Mozilla.

I use Mullvad. The map says its only relationship is a sisterhood with Firefox VPN (they use the same servers, but different software).

Surfshark worked well for me for a long time. Lots of servers, works well for unlocking region blocked content and it’s pretty cheap. If you’re into full privacy, I recently moved to AirVPN who accept payment through crypto, so you don’t have to hand over user data except for an email (which doesn’t have to be a real one, you can delete it later).
