Power does matter. It isn't the only important factor, but it matters.
Anyone who has had to take off from a helideck with barely enough power AEO to do so, and done the same in an aircraft that flies like an elevator will know that.
There are other risks and some of them may be greater in terms of frequency (CFIT for example), but that isn't an argument for focusing on the other risk/s at the expense of one that can be improved/managed.
