Orbi 770 Series

If you need a mesh I recommend the Orbi 7 series or higher have 2.5GbE WAN and LAN ports on both the main router and satellite units. A lot of WAN is 1Gbps or less, so companies like TpLink don't really prioritize the high end as much.

Tp link deco or Orbi 770, wired back haul - I have the same situation and got the 770, now I get a full 1.5gbps on all floors every room - put one mesh point on each floor (wired).

I have had an Orbi 770 with 2 satellites in a 3100 square foot house for about a year and have had no problems. Works well.

Agree with all of this. My 770 was nothing but problems. NETGEAR support was more interested in trying to get a floor plan of my house than actually helping (my issues had nothing to do with placement). They take forever to release new firmware and when they do, problems aren’t fixed and more problems are introduced.  The price is crazy for a steaming pile of shit. I gave up and went back to Eero. 

Eero. I've historically had good luck with Eero. After Amazon bought them and it was time to upgrade, I switched over to Netgear Orbi. Awful mistake. It made me appreciate Eero that much more. I picked up the Eero Pro 7 on the Prime day sale, despite being an Amazon company now. So far so good. Performance has been great. I'm not a fan of TP-Link personally since they don't have the best security track record.

I would recommend the Netgear Orbi 770 and it offers excellent coverage, strong performance for streaming and gaming, and the app is really easy to use. If you're looking for a more budget-friendly option, the TP-Link Deco XE70 Pro is a great alternative with solid value.
