A:Answer It depends on what router you would be attaching to it. This includes an integrated AC1900 router which is a middle of the line for AC routers (I wouldn't waste your time with a/b/g/n) so if you had a separate AC2400 router, then separate would be better, however if the separate was an AC1750 or a/b//n then this would be better. However, this is only a single point if you have any devices that are far away from the router or have to go through thick wall, heavily insulated or brick walls, you'll still have access problems and I would advise getting a google wifi with 2 or more points and setting up a meshed network (assuming you want simple) If you're ambitious enough and really want to learn about the tech and have time and can research, you can set up meshed networks for less than google wifi, however if you want a simple solution then go with google. Every wifi access point (router is an integrated access point) will suffer degradation the further you move away from it, a general rule of thumb in typical wood framed residential construction is that signal will reliably travel 2 rooms away (walls degrade signal) after than you're likely to experience issues.
So my conclusion if you can locate this centrally and never need it to travel through more than 2 rooms (with walls) then this is great, if not, then you'll want to consider separates, this "can" be used in a mesh network but takes some knowledge and patience. If you're looking for simplicity, then separate with google wifi with multiple meshed access points.
