I've been looking for replacement home networking gear the last few days - I still don't understand Wifi 6 vs 6E, but mostly what I wanted to say was when the Wifi4,5,.. naming came out a few years back my response was "ugh, stupid marketing" and now that I was actually having to look for hardware the difference in actually comparing functionality with linearly increasing numbers is so wonderful :D
That said, what exactly does E imply? I was really trying to distinguish devices using separate 6ghz backplane, and that was annoyingly opaque to me as a person who writes does code but aggressively avoids anything networking :D
