I have the wrt 610 and 310 and the airport extreme. Performance is identical, the interface after about 5 minutes of using either is easy. The airport has the configurable USB port and the guest network feature. Reception is the pretty much the same. The only thing I can say I dislike about the airport is the power supply. Where linksys puts the ac/dc converter at the plug apple opted to use a laptop style power cord requiring a 1x2x4 inch box on the desk or floor.
