The main difference is going to be how many fancy software features are in the router OS and how good the warranty service is.
The key thing to know is there are only 2 or 3 manufactures of wifi chipset. No matter whose name is on the plastic box they pretty much all use the chipset from these manufacture. Only intel sells actual product and even they do not sell routers...I don't think.
On very new technology like wifi6e staying with a large brand name is important because of the need for good software updates. On older more stable technology they have most the bug worked out even devices from fairly unknown brands will work well.
So the wifi part of the box will be mostly the same and all have the same coverage no matter...
