I've had a regular tp-link wifi6 router for the past 4 years and has worked well for the family. 25+ devices online and never noticed any slowness.
Recently bought a Firewalla Gold Plus to put between the internet gateway and the wifi router. Wish I had gotten that years ago. One of the best purchases I made in a long time tbh. I have the wifi router in AP mode now so the firewalla does the routing and everything else instead, wifi seems faster now that it's not doing as much anymore.
