Apple Gen 5 is a ....
Good router, very stable and very easy to set up. If you are a person that likes to just plug it in and forget about it this router is for you. It's also very stable. Apple's customer service is also top rated. The Asus is also a very good router. It does have higher throughput than the AE5 and it is very customizable. If you are a person that likes to tinker with the router settings the Asus is the one to go with.
I hope this helps to some extent. If I were you I would look at the reviews on SNB and Amazon for each of these routers. Both routers will provide enough throughput than you'll need. Good luck.
