If you want something European, I'd throw AirVPN in the mix. I went there and never to Mullvad. And now I'm glad I didn't and at the same time I'm looking forward to hearing inevitably what corpses my current provider has in the cupboard.

I dislike Proton, which I quit after the CEO praised 47 on his big tech regulation and before they handed the email account of some environmental activist over to the authorities, in France IIRC. They want to be your replacement for Google and keep pushing more services at obscure subscription levels at you. In terms of VPN, they were good though.
