You can also use their mobile app for just one AP. You scan the little qr code and setup goes from there.
WiFi networks need to be configured every now and then, e.g. to set up a guest WiFi, change the password, change the channel to a less crowded space, or activate MAC-filtering to kick my neighbours out. With LEDE I can do all of that with a straight ssh. No way I will maintain Java alive on my Mac just for this.
The tipping point for me was a bug in the Ubiquiti firmware, I systematically had to boot the AP twice to get it working. LEDE is perfectly stable.
