Which router to keep? linksys/ap extreme

[rsutoratosu]

I been powering my house plus playing with these routers for a while, going to either sell or give away these N routers

I have airport extreme model A1408, Linksys E4200, Linksys EA4500. Each one is on a different floor.. I don't really need all 3, I figure Ill keep two, Probably the ea4500 but not sure which other one to keep? The E4200 or Extreme..

They're all in bridge mode, works well...
