> The best UX in every single instance I've encountered is consistency.
While I agree that consistency is hugely important, I have also seen a lot of cases where it made the UX worse. The reason is that, unfortunately, UX isn't so simple. There isn't a single UX rule that is always true. UX design rules (best practices, guidelines, or principles) are a good starting point, but in a lot of situations multiple rules are conflicting each other. UI/UX design is dealing with tradeoffs most of the time. Good designer will know when breaking a specific rule will actually improve the UX.
Consistency is very important, but sometimes a custom UI element will be the best tool for the job. For example, imagine UI for seat selection in a movie theater ticket booking app. A consistent design would mean using standard controls users are already familiar with, but no standard control will provide high quality UX in this situation (not without heavy modifications).
But I still I agree with you that a lot of bad UX is due to inconsistency. There needs to be a good reason each time consistency broken and often it is broken for the wrong reasons.
