I use PIA because it’s cheap as dirt. I don’t use their client and I have it setup so exclusively my torrent client uses it. It works for my use case because I’m pretty much just trying to avoid nasty letters from my ISP. I wouldn’t trust them with any of my regular traffic because they’re sketchy and there’s got to be a reason they’re so cheap.
Although I would consider what your usecase for a VPN is - ie what attack vectors are you trying to protect against when using it for regular traffic? There’s arguably very little a VPN does to protect you on public WiFi and also opens you up to new risks
