Hotspot security (WPA2, WPA2/WPA3, WPA3), which one is the best/fastest? - eviltoast

Have searched about it on the net and have seen that WPA2/WPA3 is recommended, in the case of older devices n IoT.
I normally use the hotspot to share internet to other devices. They’re not too old and I don’t use IoT devices.

Would choosing WPA3 be better/faster for my case? Did not see much info on that or benchmarks about it?
Saw somewhere that WPA3 has more overhead because of greater encryption, but would plain WPA3 be better than the default WPA2/WPA3?

Thanks in advance
