Ignore whatever anyone tells you because environment factors matter most. And they don't know your environment, nor did they ask which tells you something big. Best advice is. If you don't need mesh, don't use it. Get a very good single router if it covers your house. Which most highest-rated routers can for most people. I have a difficult house: odd shape, several large steel beams running throughout but I do have ethernet backhaul all over so my experience is having tried location with and without ethernet. Quick results in my 3 level, 3800sqft. Two old Asus AC68 (top and bottom floor) had best coverage inside and outside the house, by far. Roaming was crap so I wanted to try others. Unifi was ok with one AP but literally stopped working when I added another. Fought it for two weeks with expert help. I tried TP Links new Wifi6, it was horrible in every way. Running Orbi 50 Series now. It's so-so. Has good Dbm coverage inside the house but doesn't go into the yard at all. It still drops/reconnects cameras often. The firmware is super buggy. had to install Voxels to get it working stable. It's not fast as the asus, about 20-30% slower in actual use. NOT impressed at all with Orbi. But it is better than the Unifi and TP was in My House, YMMV. Plus Netgear support sux. 90 days. No exceptions even though I had problems since day 1 I'm going to back to ASUS with one upgraded to a newer model and using the older for the remote AP. I'm expect, based on the initial Asus setup, I'll get better coverage and stronger signal than Orbi.
