I've really enjoyed Torguard so far, althought I switched very recently.
If you decide to use Torguard, USE AN AFFILIATE CODE FOR 50% OFF. I used Tom Spark's (YouTubers) code, but Torguard makes it really easy for any creator to generate a code so use whoever's you'd like to support.
EDIT: It has a linux gui, which oddly must be run at root. I added a line to create an exception for only my user to be allowed to run /usr/bin/torguard as root without a password in /etc/sudoers, and it works as expected.
