Question about Netgear R7000 and Qos

Hello, Im looking forward to buy a gaming router with application qos. I bought a netgear R7000P but the problem is that the QoS this router uses is by device not application so its pretty useless in my point of view. My brother watches Netflix and youtube in Xbox one and the router prioritizes it. The best qos settings I have used is Linksys. It gives certain applications a specific bandwith and when I stream theres absolutely no lag. Im looking something similar to this. I have 20mb/s of download and like 5 of upload. Thank You.
