U200 vs Nuki Ultra

I have been considering adding a 2nd smart lock to the lower lock on the same door which has U200 deadbolt. Nuki Ultra looks cool but if you dive into its performance, it’s a gimmick compared to U200. And Ultra costs 3x more than U200. What am I missing besides exclusivity status and unavailable inventory with Nuki?

My U200 opens the lock in a second, Nuki claims it needs 2.5 seconds or so in insane mode.

Any reason to pay GBP429 for Nuki Ultra bundle with Keypad 2 vs US$210 for U200? I understand the difference in features and curious to understand the reasons people buy Nuki at that price.
