Mullvad, it performs well and I feel that the ability to pay cash/crypto, the lack of subscription both are tangible signals that they are real about anonymity.
Proton, with their Secure Core features is pretty nifty and I like that they have other products that shoehorn into "getting away from being spied on" by providing mail/calendar/drive storage as an alternative to Google. Their drive product could use some work but overall I'm really happy to pay $10/mo for VPN+custom domain mail+500GB of available cold storage.
Thanks for the background on the industry.
