N55 also comes with dual clutch which is good for hard driving with corners.

Not sure I agree the n54 is overrated. I have an n54 135i and an n55 x1. N55 is a great motor but I'm more worried about the N55 long term and it would take a turbo swap at the minimum to get it to where my stock turbos n54 is.
