I can't speak from experience for most of these, but I just bought some Ruckus APs and have been through review hell. The Ruckus APs were clear winners; the reviews (of the R500 and R600) were glowing and said the devices were easy to configure. (They're also very expensive.) They haven't arrived yet, so I can only recommend them based on my research, not based on experience.

I'm replacing a hodgepodge of hardware, including some Apple routers and APs. The Apple products worked reasonably well. I had to keep them fairly isolated (for heat) or else they required reboots. But given their price point, I would probably look somewhere else.

Throughput was a major complaint for many reviewers of the Unifi models I researched. No individual reviewer convinced me the units themselves were the problem, but the sheer number of such reviews did.

Peplink's Pepwave units look awesome and were my second choice.

For all the others, I could either not find enough reviews to reach any conclusions or could not find a model that fit my needs.
