I think that MikroTik does everything to make managing their devices unclear as it's possible. WinBox for example, in some places looks okay (e.g. presenting data in tables or drawing charts) but filling forms or editing settings is terrible. It's not about Ubiquiti, but even pfSense does great job when it comes to presenting data and help to understand presented data (e.g. hide/show advanced options, providing comments and documentation to each option in forms, using padding and margins even help to understand visually your options).

But in the same hand I need to say I am impressed with MikroTik CLI. It colorize each typed word! Even enterprise class Cisco devices don't do it. It's super useful for me and help me with understanding what's going on. Do you even imagine programming in notepad with note type of font and color today, like it was in the past with Windows Notepad? I don't think so. UX/UI is not only about pretty buttons. It's about usability, repeatability, predictability, stability, confidence and ease of access. A software with best features is useless when it doesn't provide any convenient and trusted way to reach this features.
