Both Zero Handoff and Wireless Backhaul for Wi-Fi have proven to be
*not useful* technologies for us due to the transient and unpredictable
nature of Wi-Fi interference. Both technologies have correlated risk
factors that cause cascading performance degredation. As interference
or load increases, the probability of adverse loss, jitter, and latency
also increase. That breaks the network's suitability to many applications.
SNR in the backhaul band can be fine for days, then can become absolute
shit for hours, seemingly for no reason. Site analysis shows an energy
spike in the backhaul band. Maybe somebody's 'smart' AP has changed
channels. Maybe someone is microwaving a baby monitor. Maybe the UFO's
just outside probe my brain using the Wi-Fi bands to steal my secret
plans. Architecture using these technologies can be acceptable for
hobbyists, or for when there is literally no other option within budget,
but IMO architecting a system with them is similar to setting out for a
day on the ocean with a life jacket (i.e. no boat).
Zero Handoff?
This we've measured less carefully, but performance appears to tank far
sooner in this scenario too. Please chime in if you have specific
expertise on this technology, but this appears that ZH depends upon low
interference on a single channel across the entire handoff 'campus'.
That's a pipe dream in dense condominiums and high-rise office
buildings. It may be OK if you live in a Faraday cage or on a drilling
platform in the ocean. Apart from those scenarios, we've never been "on
the fence" as to whether we should use it.
Now AC on the other hand... I love me come AC. Plus, they tend to
serve double duty as space heaters.

Be aware, though, the UAP-AC is missing some banner UniFi features.
No Zero-Handoff
No Wireless Backhaul
I can't tell if any of the UniFi indoor stuff does the UNII-2e/DFS
stuff. The AC's certainly don't.

Does anyone have any recommendations for small office access points?
I second both of the previous replies. I use Unifi and Tomato
exclusively for wireless.
For budget installs with plenty of features, try Shibby's Tomato on
the ASUS RT-N12 or RT-AC66U.
For POE, top aesthetics or mass deployment and central management,
spend a little more on the Unifi.
