I've been using Mullvad for the past few months. Have not had many issues with it aside from the 5 device limit and the removal of port forwarding. I'm currently looking at Private Internet Access as a potential replacement. It looks like it offers 10 device limit and port forwarding included with the price.
Anyone using PIA? How's the experience?
Edit: Probably should have mentioned, feel free to offer any other recommendations, I'm not attached to, or against any specific recommendations. I would like it to have a GUI available on Linux though if possible.
I switched to AirVPN after finding out that Mullvad disabled port forwarding.
I have heard rumors that the did that because of people hosting cheese pizza via their VPN accounts.
The performance of AirVPN does vary, I had to try a couple of countries before I found a server that didn't throttle me (and I only have a 50MBit connection).
Maybe I will try Proton in the future, but then I would have to commit to a 2year subscription or pay a lot more.
