I also like that they let you download the raw wireguard config files so that you can connect without having to use their client. You can just plop them onto your filesystem and use wg-quick to get going.
Since I'm also a ProtonMail user and I considered switching to them for VPN as well but their python client doesn't seem to work correctly on my Arch Linux install and it doesn't give me anything useful to debug it beyond "An unknown error has occured" so I couldn't be bothered to investigate beyond that.
