They might be better technically, but those things are always a PITA to set up, troubleshoot, upgrade firmware, and maintain (especially if you are giving one to say your parents in a remote location). So easy to set up and monitor Airports from a Mac or iOS device.
Yeah, I know you are gonna say you've never had a problem with yours, but that is b.s.. I have dealt with dozens of these Netgear, Belkin, Linksys type routers and they are always total pieces of crap that have annoying issues. Tried it so many times and I am done with them. Airports are maybe not perfect, but they are by far the easiest to just get things working.
