Recommend a VPN for Android?

I’m looking for a VPN service for my Android since I’m on public wi-fi a lot and want to buff up my protection. Right now I’m considering Surfshark because it uses IKEv2 protocol and it’s stated that it drains less of your phone battery. I searched but couldn’t really find other VPNs that offer IKEv2 for Androids, maybe you have some recommendations so I can do a comparison?
