Wifi 6E vs Wifi 7 Router Purchase Question - Help appreciated

Hey all, just wanted to ask a quick question about a purchase decision I have before me.

I am currently using a Tenda TX9 router for a PCVR setup, however the network lag spikes have been less than pleasant and I am almost certain it is the Tenda's router's fault for constant lagging and stuttering. I would like to buy a route that will be able to give me sufficient capability to run a PCVR (as a dedicated router) for now, however with the intention that I will be moving out in a few months time to be repurposed as a main router in a home (currently do not require it due to provided wifi at current place).

I have come across these 2 products which are of similar price here in AUS at the moment:

- TPLINK GXE75 - Tri Band Wifi 6E https://www.tp-link.com/au/home-networking/wifi-router/archer-gxe75/

(AFAIK this may be idential to the AXE75)

- TPLINK BE6500 - Dual Band Wifi 7 https://www.tp-link.com/us/home-networking/wifi-router/archer-be6500/

My question is:

- Is the dedicated 6Ghz band worth it for the 6E router over the futureproofing of the Wifi 7 in a few months - year's time?

- Is the BE6500 even a router worth purchasing as the primary home router or would something like a BE550 be more worth to save up for? (Only 2 people will reside at home).

- Will the Quest be fine with a reverted Wifi 6 on the Wifi 7 router? Just having issues with the TX9 and I live in an area where this device is the only 5GHz wifi signal around (Checked with Wifi Analyser, my Tenda is literally the only one)

Appreciate your input!
