You are forgetting that even with the 2x slowdown you talk about, bitboards are
still breaking even with your method. So it's your_method + 33%, not
(your_method / 2) + 33% as you would like it to be.

Bitboards are extremely more elegant IMO, but that is only a matter of opinion,
and serves no purpose to "proof" one method better than another.
