My advice is, if you have the money to invest in a new WiFi router, use that money instead on a contractor that can do lan cabling in your home. It will cost less than $200 for a long distance Lan cable straight to your room or wherever.
Then, you can enjoy this kind of break neck speeds for your laptop/PC and definitely for your PS5.
As for WiFi, unless you have true WiFi 6 devices which actually needs a lot of antenna in said device, your upgrade to WiFi 6 will be a disappointing one. Especially for phones which might still not achieve the full WiFi 6 capability.
Just go and search YouTube review or test videos where they show you the WiFi 6 router that some people have mentioned here and see the kind of results you'll get with actual home usage. Take note, our walls are mostly bricks and not drywalls. So you can further decrease the speed from what they get too.
As for lan cabling, I did it years ago as recommended by a thread on HWZ.
Or something like this one.
