Mullvad any day. Support is awesome.
If you go with Mullvad look for the gift cards out there that are for 6 or 12 months of service. I grabbed one off Amazon.ca for 12 months at $75. Works out to be cheaper than paying per month with the ever changing exchange rates.
I also like the fact that Mullvad has servers in the city I live in where as Proton has them on the west coast or east coast. Not the greatest for those in the middle of the country.
Make sure it’s “Sold by Mullvad VPN” and “Shipped from Amazon”.
