Haven't heard of private, but I would highly recommend airvpn. You could do qbittorrent nox on an old computer for good seeding. If you want I could elaborate on how, but I can't right now.
I wrote what's before this before looking at private. It looks okay but they definitely make some false claims in their marketing that make me skeptical. They say their VPN can make connection faster than non-VPN, that is only true if being throttled or smthn weird. They say it hides your IP from your ISP, which is impossible. Your ISP loans you an IP, of course they know it. I know they mean it allows you to use an IP that your ISP doesn't know, but they still said it wrong so.. idk im rambling and tired but... yeah.
