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

I got this. But I stopped getting updates like 2 years back. Is this due to the costco model?

Negatives.
No method of manual channel selection.
All of the mesh devices use the same channels as all other ones, not just for the 3rd backhaul band which is required to be on the same channel. No, mesh networks, roaming or fast roaming (802.1k/v/r) does not require all APs be on the same channel, they should not be for best experience and least interference.
Control of devices only through the phone app.
Backhaul 3rd wireless band appears to stay up and active as a "hidden" SSID taking up channel space even when using in all wired backhaul mode.

Positives been using a 3 pack in house in AP only mode backhauled with no issues and very stable. Can't speak for using them in router mode. I've had some issues with fast roaming on some things but that is devices specific, not the fault of the M9 specifically.
this is very helpful, thank you. I need something in AP mode that boomer simple for my mom's place.

The only noticable enhancement with WiFi 6E is more channels using the additional 6GHz band so unless you have a huge number of devices or need more channel space for greater bandwidth, WiFi 6 is going to be suitable enough. WiFi 6E is a hardware upgrade so any WiFi 6 or below devices won't be able to use the 6GHz band. I think WiFi 6E will be more applicable for users in a business or large consumer setting like sporting events.
6E is already available for consumers now and there are already 6E devices, Galaxy S21 Ultra for example. It's pretty much the same situation with wifi6, only my cell phones support it. Just doesn't make sense to do a half step upgrade.

M9 plus from Costco with wired back haul. Don't try this at home, you will be disappointed in your results.

Here's mine, just installed 2x Deco W3600 from Walmart for $129. I have Gigabit internet, would I be better off with the M9???

I have this mesh system, man they get so hot. I wish theres a fix for it.
I have mine on its side and so far barely gets warm. Not mounted on walls but I improvised a wire stand. The mountings on amazon costs too much for such function.

Is this like a huge noticeable upgrade from M5 mesh (what I have currently)?

The most critical thing in a WiFi Mesh is the communication between those pucks/satellites.
In your case what you have done is the correct thing. that is to wire them instead of relying on wireless as inter communication link between pucks/satellites this helps improve performance of any mesh system by far. That is why your network handles all that traffic without a hitch and will continue to do so until you come across a situation where you run out of the bandwidth goog wifi gen 1 offers on wireless

So, I have a great router as far as speed and management, but wanting to get extra range for wifi. Can I run a cable from my existing router to these as sorts of satellite range extenders for WiFi? Or is this more of a stand alone?
Exactly what backhaul means, i.e. you connect an ethernet cable to one of the satellite's mesh and extend your wifi without ever changing SSID or Log ins (auto roaming). This Mesh connects to your wifi router in two ways, ethernet cable (backhaul) or wifi connection (both extends wifi). In my case, I just decided to backhaul the first satellite and then connected the other two via wifi from the first satellite. And totally disabled my router's wifi and just used its ethernet connection as a switch. Almost a year and no issue so far. Ethernet backhauled satellite speed is around ~400mbs while the Wifi connected ones are at 100~250mbs. And I have the GB cable subscription.

How's this compared to the nighthawk mr6 3piece mesh Costco selling too
I have the Nighthawk MK63, very pleased with performance on current firmware! Great price point (@Costco) for a premium product.

I have these for myself and my inlaws, they're great.
However, the whole point of a mesh is easily adding nodes, and apparently these are not findable as single pucks. I need one to extend the inlaws' for their outdoor cameras.

Anyone know the best way to get a single puck of the M9?
It's not really "worth" it to buy a single. They do sell single m9s but you might as well splurge just a little and get a couple more
