My point is that it's irrelevant at this point, as those machines do not yet exist. The existing experimental setups and theoretical models are most closely related to boolean circuits (vs a Turning machine or a RAM machine or lambda calculus or whatever is your favourite computation model). But you can still show gains on some sets of problems (like integer factorisation).
