I roll my own using a VPS in a different country that has a policy that shits on DMCA. Since all I need is to evade copyright letters when torrenting. If you need the utmost privacy, go with Mullvad or IVPN. Both do not have an account tied to anything and they don't save payment info. They also accept crypto if you're into that too. No port forwarding sucks, but I don't really bother with it on my VPS and still can torrent.
Don't know about ProtonVPN's policies, but AirVPN, I'm pretty sure lets you torrent without getting hit with copyright notices. But the former two I mentioned above are the absolute gold standard if you want privacy. Do keep in mind you'll also need to use a browser that conceals your fingerprint too. That's almost just as, if not, more important than just getting a VPN and connecting to it. Librewolf is what I tend to go with because it has a hardened user.js out of the box so that you don't need to keep up with changes upstream from Firefox as far as Mozilla killing/changing features go.
