In general try to go for Asus, they can mesh and are usually reliable.
If you want something more advanced, look into Ubiquiti, though they will be more expensive, also read the reviews for the different components, some POE switches can get quite hot, so if you don't need it try and avoid it.
I am on Asus, and have had very little issues related to my router the last few years, but have been eyeing Ubiquiti lately...
Had an asus mesh system with three different routers for a bit. Worked really well! One of them died though so bought a refurb asus mesh system off Amazon for like $100. Great speed and coverage for a year now no complaints!!
Asus puts a lot of their advertised features behind accepting terms and conditions that have them harvesting and selling your data. You can not agree to it and still use the device. But many of the advertised features won't work.
I also second this. I have an Asus router setup with mesh nodes, and it has been running smoothly, especially since I'm hosting a plex server and occasionally multiplayer servers.
