It totally depends what your requirements are, feature wise. There are pros and cons with every router. You choose what's good for you.
The Netgear R6300 is a top router, comparable in performance (according to the reviews) to the Asus RT-AC66U:

Speeds are blindingly fast IF you use the right adapter/network card:

So to make the most of this router you should use either an 802.11ac or dual-band 802.11n wifi adapter/card.
Most laptops are fitted with cheaper wifi cards that support 300mbps or less and most that do support 802.11n are not dual-band, so cannot use the 5ghz band for better speed and reduced interference.
I recently bought the Intel Ultimate-N 6300 wifi card that is used in some of the review tests. Got it off amazon for £20 new. This card is a three-stream (450mb/s) card so would work well with the R6300. To get the max performance out of the R6300 you'd need an AC adapter though.
I have a 120mb/s Virgin broadband connection and like that I get my full wired speed over wifi.
You can see some speed tests here with different adapters and how much difference it makes:

If you have a LARGE house, 100mb+ broadband, multiple devices that use wifi with adapters that can support the higher speeds (such as AC or 5ghz 802.11n adapters) and want the best of the best then I'm sure it'll be a good fit for you.

Most high-end routers have gigabit ports for ethernet, so as long as your computer has a gigabit network card (10/100/1000) you'll have no problems there. Just make sure your cable is at least cat5e or cat6, so that it supports gigabit speeds.
