Big fan of ubiquity APs myself, but you may still want more than one AP depending on how many clients you have. I am at about 13-15 clients once you add everything together and I find my spectrum a little crowded. The range on the LR is fantastic though, it reaches to a block away from my home when turned on high (I lowered the signal strength), not that my devices have a strong enough chip to talk back to it though.
I bought the most likely overkill UAP AC HD to solve for the density problem. https://unifi-hd.ubnt.com/ At the time, I was under the delusion I'd be building a smart home. I have since dialed back my requirements but have (hopefully) excess wi-fi capacity.
