I went with Costco Orbi RBK 753 and extremely satisfied, no speed loss at wireless satellites. No reboot needed for almost two years. Just ask yourself why the Orbi is almost doubled the price but Costco still offers them?

Blows it away in terms of value to performance.

The M9 offers an overall higher potential maximum throughput by having a third band (5Ghz fall over and dedicated wireless backhaul.)
Not knowing your specific network and usage profile, generalizing, the average 3-4 person home user will not notice a difference between the two.
That said, the M9 is your go-to choice if you are going to use wireless backhaul between the APs as the M5 (dual band) has to share the 5Ghz band between backhaul and user traffic.

Google is your bestie for more details (examples:)

The best mesh router I have ever owned. Worked flawlessly until I got super greedy and spent 2K on wiring the whole home and installing TP Link EAP-660HD AP (TP Link earned my trust via M9 Plus and I didn't even consider Unifi or Zyxel or anything else).

BTW, this is much faster than crappy Google mesh system, including the newest one (I used nest mesh for few months before getting M9 Plus). Two of my extended family are still using M9 Plus and it still work flawless for them.

You are expected to get around 550 to 600 Mbps on the main router (YMMV based on your wireless interference). If you wire the satellites they will also get you same sped. Otherwise speed will be based on wireless link speed. And M9 plus has tri band. So even wireless linking works flawlessly. I was pulling close to 400Mbps in my office and on very far end of the house I was pulling about 250Mbps.
I have a 3950 square foot house. I have a 4 pack of the gen 1 Google wifi. I have computers, TVs, kids tablets, smart switches and outlets and bulbs galore. There's nothing crappy about Google mesh. I do prefer it had remained in its own app instead of being smashed into the Home app. I did install the wiring myself to each one (modem->router->switch->satellite pucks). I've never had a speed issue or failure or any problems.
Also replaced Google Wifi 1st gen with these. Huge upgrade. These routers tend to get hot underneath so best to elevate them a bit with stick-on tabs or find another solution to let them breathe easier

These work well in a 3500 sqft home with three floors. We get a signal outside for 50' maybe more. Only drawback is they are not Wi-Fi 6.

I've had these for a year or so. Fantastic units with Tri-band (if you're not hard wired to the other units).

I bought this and love it. Ethernet backhaul. It's fast, reliable, easy plug and play. Recommend.

How does this compare to the NETGEAR - Nighthawk MK63 AX1800 WiFi 6 Mesh System includes Router and Two Satellite Extenders for $170 and is available in store?

It's been this price for a while. Recently bought and performance is ok. Need to make sure they connect in the right order- for example, in my house it needs to be basement (Ethernet connection) -> office (middle floor) -> bedroom (2nd fl) but sometimes bedroom connects direct to basement and the connection is slow. Need to reboot

Sorry I humbly disagree. Depends on what level of perfectionist you are. My nest router packs failed to do proper band steering. Clients would often get stuck with 2.4 GHz. Also, signal was weaker than M9 plus. Speed was also much worse (I would be lucky to get 300Mbps) as it was not a tri band. If you are not a perfectionist, even 100Mbps would be fine. I am just OCD about my wifi. M9 plus is miles ahead of nest Wi-Fi.

The M9 Plus is on wired backhaul and more reliable but not as fast as my Netgear Orbi RBK53 system. No subscription fees for security. It needs to be rebooted once a week to keep the 40 devices on Google Home happy, so it's not perfect but I don't mind.

The smart hub is extremely basic and not useful with my configuration. The list of compatible devices is dwarfed by Google and Amazon. Three out of my forty devices are compatible with the hub so I can manage them remotely outside the home, which is nice, but only the three...

My 4400 sqft home is on 1Gb fiber and came pre-wired with CAT 5E. It's ready for the same business class upgrade as @frugalandrich when I figure out where to mount the Omada AP's.
