Cost, ease of use, speed, other good features, etc.
Mullvad or Proton. IVPN is also good.
I use ProtonVPN whenever I download a lot of Linux ISOs.
I have a lifetime subscription for Windscribe, so I’ve just been using that with no issues for years. I’ve recommended it to some other friends and they’ve been fine.
I also pay for Proton services, so I have ProtonVPN, but I’ve yet to try it for torrenting.
Mullvad or Proton
Note that Mullvad no longer allows port forwarding, which can make it harder to torrent effectively
Is it really that bad? I haven’t had any issues torrenting stuff with Mullvad, although I usually don’t torrent files above like 20GB
It reduces your available peers. You can’t connect to other people with closed ports, one side needs to be open.
It isn’t a huge deal with popular torrents, but it can cause problems with unpopular/old stuff.
I pay for Proton Unlimited so I use Proton VPN. Getting port forwarding to work on Linux is a bit of a hassle but they have steps on their website. It’s hardly any slower than my internet connection, but that’s because I’m on the paid servers. The free servers are rather slow. They have a graphical client for Windows and Linux.
Proton Unlimited is €12.99/month. The VPN has a good number of features and you get the whole Proton suite with it and 500GB of storage. You can pay for just the VPN which is cheaper if you don’t want the rest of Proton.
