Yea I use mullvad at the moment and quite like then ... there's a LOT of sketchy and generally slimey VPN companies. I dont know of nord being bad per say, but I heard they got hacked last year or something. Its cool that they're using wireguard now though. I would say specifically stay away from Private Internet Access and the other ones owned by that same dude (Cyberghost, ExpressVPN and Zenmate).
