Longest I’ve been with is Cotse, although US based I trust Gielda is all it boils down to reference that topic.
Mullvad best speeds and experience with (especially when using their wireguard service)
AirVPN is fast and reliable and although their available client leaves much to be desired it does work well and supports other carriers (on Linux, beta version, also mono based so not good for many threat profiles I imagine).
PIA, via significant other’s laptop, I don’t trust them - too big and too sleazy with their smear tactics (although the stuff they expose on competitors does seem to hold water.
Yes, all my VPN providers are in 14 eyes territories but I am not concerned over big brother (and hiding my activity from gov, tla’s etc), rather about the “big other” monetizing me and my every move on the internets (eg. 3rd party/trackers and the proprietors of and the profiteers from surveillance capitalism).
So really VPN is just a privacy filter in my case use, with each VPN provider I do have currently used for different reasons (during this overlap subscription period).
For any measure of anonymity into the clearnet then Tor network and browser, along with different habits, must be used. (and definitely No VPN+TOR together)
