I thought the 5ghz would be better, but it's blocked more by floors and heavy walls in the way of the signal. It's faster when I'm reasonably near the transmitter, and okay throughout the house.
Yeah 5GHz can carry more data per second thanks to the higher frequency (and wider channels) but the downside of that is more susceptibility to blockers.
My wifi mesh has the same SSID for 2.4 & 5 and not had an issue with any “2.4 only” devices.
