I used protonvpn but been trying to find a replacement that's reliable. A friend also told me about that VPN but haven't really checked them. Maybe this is a signal I should.

I used Mullvad before and will definitely will use it again when I have the cash to do so.
I don't know if it's the most private one, Maybe the most anonymous, at least for what I've hear self hosting is the best way

But Mullvad seems like the best one that a beginner like me will choose and that's a good thing!.

I also like the fact that they don't have referral/sponsorships like all the other VPNs have and it's a fixed price for 1 month and 24 which doesn't make you commit to it.
