Sorry to reply to such an old thread, but I have had both devices "side by side" in the same environment and can say for my experience, there is simply no comparison. The ruckus devices, 5 in an unleashed deployment, are rock solid with great performance; handoff is reasonably seamless (there's a end user device component here, so not entirely up to the infrastructure). The ub devices were flaky and quirky, still far better than the sit on the table home router, but even with a small user base, I wouldn't deploy the ub in an environment where bandwidth will be taxed. Standing in the same place with different WAPs in the same mount in the ceiling, my single antenna AC phone would get 180-200Mbps on the Ruckus and 40-50 Mbps with the UB AC. Not to mention the nearly full enterprise management features that the Ruckus adds. There's certainly a price difference here, so you're paying for the better device, but in the long run, I'm very happy to have switched to Ruckus and would make the same decision again.
