My Airport Extreme goes YEARS without me touching it. It took me a couple minutes to set up. I very much doubt that Ubi's ease of management or use is superior. Equal? Maybe. Superior? Nah.

Have you ever set one up? They are insanely easy to manage and use. Superior? Likely. Ubiquity has amazing software. I set up 2 edge routers recently, they never need to be restarted. Also, the newer firmware has really good setup wizards for the basics. Almost impossible to screw up.

I've had significant issues with both Uniquity and Apple APs, so I wouldn't necessarily say that one is that much better than the other.
