Privacy-focused VPN service

The purpose of this topic is to exchange information about privacy-oriented VPN services.

Currently I am using Mullvad. Are there any other VPNs you would recommend?
IVPN has a buggy Linux desktop app and is unstable; ProtonVPN depends on NetworkManager.

Currently, I am not unhappy with Mullvad, but would like to know of alternatives in case Mullvad becomes evil in the future.
