I have a ea8500 and i'm very happy with it. I test routers and i found the ea8500 the best. I have triband routers and they dont have the speed or distance that a mu-mimo router has. Make sure you get one that has a fast processor and good amount of ram. the ea8500 has a 1.4 ghz processor with 512 mb of ram. I notice a great speed jump when using youtube and downloading files. Another good router is the wrt1900acs, but it is a single user mimo router and has a 1.6 processor with 512 mb of ram.
hope this helps
