Everyone uses either CLI or WinBox GUI app, which is excellent. https://wiki.mikrotik.com/wiki/Manual:Winbox#Work_Area_and_c...

>horrible to manage and lack features users expect

Users expect WebUIs, and WebFig is horrible to manage.

Users expected faster horses, got cars. WinBox is so much better than any web UI I've ever seen, didn't know I wanted it before I had it.

1. WinBox only works on Windows. 2. Android version of WinBox is buggy and also only works on Android 3. It may be better if you have expertise in network administration and know RouterOS inside and out. Most people who buy Ubiquiti gear do not, but their needs aren't met by regular consumer routers which do not allow any kind of "prosumer" settings.

MikroTik may well be better for you (I used it for 5km PTP links, but that's because it's cheap, if I had the budget I would've gotten LiteBeam or AirGrid), but that doesn't imply it's a suitable replacement for everyone. And it is most certainly not a suitable replacement of airOS for most people who use airOS.
