If you need stability, go with a high end consumer router and load OpenWRT/DDWRT on it. OpenWRT and friends are very stable, but don't often take advantage of advanced features like automatic channel selection, traffic prioritization, or beamforming.
If you absolutely need features, go with a ubiquiti AP. My only issue with them is their hardware leaves a lot to be desired, and is rarely powerful enough to cover a full home, this isn't necessarily ubiquiti's fault though.
Business class APs expect you to set up multiple APs in the office, so their hardware is typically a lot less powerful than what you'd see in a consumer wireless router. A ubiquiti AP will gladly cover your 1 bedroom apartment, but don't expect it to cover your 3 bedroom home
