i see cos now can early recontract, they give wifi 7 router.
so just upgrade to 3 Gbps will be good right? but if got $29.90 for 10 Gbps, is it good to take?
If you really like to go with 10Gbps, just go ahead.
You can still keep using the Asus ROG GT-AX6000 in this case.
Or as I mentioned, get one RT-BE92U and use it as the main router for the 10Gbps plan and then use GT-AX6000 as the mesh node, no need to go with two RT-BE92U or two ZenWiFi BT10.
ZenWiFi BT10 is a better in terms of wireless spec than RT-BE92U but you may need to add a 10Gbe/2.5Gbe switch as it does not have enough LAN ports for your use case.
RT-BE92U may be easier for your use case since you do not seem to have 10Gbe capable wired device.
BTW, do you have WiFi 7 capable wireless devices?
In the end it is your money your decision.
