AirVPN vs Mullvad which should I use?

I am thinking about changing VPN, I am currently using ProtonVPN and I was thinking about changing to AirVPN (for its prices and port forwarding) or Mullvad (Everyone says it is better regarding privacy but I don't know why).

Which one would you recommend and why? I have seen a lot of criticism towards AirVPN for being based in Italy, but if they don't collect the data as they say they do, there shouldn't be any problem, right?
