Bought this to try to get signal out to the back porch where the Comcast/Xfinity Cisco branded gateway would not reach, nor would an Apple Time Capsule Gen1, even with a Airport Express extender right against the back wall. The X8000 will reach the back porch on 2.4GHz "N". One tip, I get terrible 5GHz performance when letting the router decide on traffic management on the two 5GHz radios. I think Netgear knows this as it comes out of the box with 3 SSIDs visible. I would not use the "Smart" traffic manager on 5GHz and use your head to make the decision of which radio to use, use 5G-2 for devices with 802.11 a/c, and anything that has slower radios like the b/g/n radios, stick them on the 5G-1 radio if they are close to the router and put anything that has signal issues on 2.4GHz if they are further away, lower frequencies penetrate walls and obstacles much better than higher frequencies!
The Netgear web interface is pretty simple, setup is simple, true gigabit throughput on Cat5-e and Cat6 (figuring overhead) and around 880Mb/s on the 5G-2 radio using 802.11 a/c clients. You can also download the Netgear genie software to run on your computer to get immediate notices of issues the router wants to alert you to.
Last note, make sure this thing can breathe, dont put it on anything but a flat hard surface and dont put anything on top of it, it will get crazy hot and start malfunctioning or just shut off, it has 3 radios and 4 processors in it. Ideally, also maintain a 3 foot gap between the router and any other electrical equipment/ adapters/ home security hubs/ smart home hubs/your computer/NAS units/ flourescent, or LED light bulbs, these all put off EM radiation and the quality of transformers (wall warts) of various pieces of equiment can be vastly different, I had one that was so badly made (big brand name on it, too), that it reduced the range of the 2.4GHz WiFi to about 5 feet due to RF jamming. Non Apple or Samsung made USB phone chargers are notoriously noisy and often a fire hazard as well. You get what you pay for. I've also seen them SEVERELY reduce the range of cellular devices while working in the field. If you have issues of this sort and moving the router away from all these sources of EMI, there are other options, you can buy high quality adapters for just about anything with interchangeable tips to power just about anything.
Hope any of this helps, but the main gist is that the R8000 is a great router, they best I've ever used and the aggravation it has saved me from justifies the premium price.
