Best Mesh WiFi System

I use and like the Eero Pro 6 Wifi mesh network system for the following reasons:
1. Stable system with up to 1GBps download speeds. 2. Very stable. 3. You can use multiple mesh routers. You are not limited to a certain number of them. 4. Regular firmware updates. 5. Excellent and available support. 6, easy to configure and setup a system. 7. Offer Secure+ system which furthers secured your network. Comes with subscriptions to multiple free useful software. Regular discount coupon codes available to reduce the annual cost of this service. 8. Ethernet ports in the rear of each Pro unit (2).  9 Some integration with Amazon. But not tight or intrusive. 

I went with the Wirecutter's top pick. Their report educated me, too. https://www.nytimes.com/wirecutter/reviews/best-wi-fi-mesh-networking-kits/

doni has already made a choice, but for others who may be interested...

I've been using Asus routers for many years (over a decade easily), so I am partial to the brand and accustomed to the user interface. About 5 years ago when Mesh came on the radar (for me), Asus did a really cool thing - they pushed a firmware update that added Mesh capability to routers that had the hardware to do it. This firmware update allowed Mesh for our home (for free), which has 4 routers covering a 4,000 sqft home and 1 acre of surrounding land.

A while back, I was having WiFi connection troubles with a NAD unit and other devices on a particular router - after struggling with it for a while (Cat cable tested good), I re-terminated the keystone wallplate punch terminal and WiFi has been rock solid on that router ever since.

BTW, two of the 4 routers were 'factory refurb' purchased at discount - I've had no problems with those. I think many people are confused by these types of devises and return them to let their ISP do it - so bargains are plentiful. For myself, I appreciate having all the control over my cable modem and routers, and Asus really shines when it comes to user-controls. I also appreciate the built-in NAS functionality, TrendMicro security and deep-dive usage reporting & statistics (with graphs and history) of these routers.

I highly recommend Asus, one of the few companies that has consistently exceeded expectations - for me that is rare.

For Posterity: 

I ended up with the Linksys Velop 3 node.  Hard wire node 1 directly to router/modem and place in in line of site of 2nd node that sits at other end of house. Then 3rd node at the rig and in line of site of 2nd.  3rd node is hard wired to streamer.  Put the router/modem on a LPS. On  Occasion the router/modem flakes and requires a bounce but other than that its been purdy solid.
