depends on the user. The short answer is it’s worth it if your wifi airspace is very congested or if you have a use case for wifi 7 speeds, such as moving large files around your LAN often.
The 6ghz band has poor range but this can be a benefit actually. It means your neighbors 6ghz signal can’t flood your home like their 2.4ghz and 5ghz can. So there’s very little interference on the 6ghz band. This also means a more stable connection and a little lower latency.
If your wifi works well today i wouldn’t bother upgrading. Unless it’s a fun hobby purchase.
