FP Scientific&Basic Calculator holds the better App Store score, 4.6 against 4.0.

Written reviews complicate that: 69% of FP Scientific&Basic Calculator's written reviews are positive against 100% of WormHole VPN's, so the app with the better star average is not the one people write more warmly about.
