I heard good things about NordVPN and ExpressVPN. I've been using PIA for a year and it's about to expire - hence trying to decide what is next!

Advantages of a service seem to be location switching, good apps, cheap, and IP mixing.

Disadvantages are that you have to trust them not to keep logs, and lots of Cloudflare captchas, and they would seem like a good target for being compromised by the government.
