The reasons I think it's nice:
- The metallic feeling of the passcode pad makes me feel secure. It's apparently borrowed from Brushed metal
- The orange "Send" Button together with the orange transaction preview made it super clear what I am confirming and where should I look for mistakes. Note that Orange here stands for BTC. Eth, for example, has a different colour
However: I don't see the USD value on this screen, which might be just fine because I saw the USD value on the previous screen.
