I don't know which would be more disorienting in practice - but I suspect that without extensive training, any high frequency strobe mode is bound to be disorienting for both the operator as well as the recipient.Don't you think it would have made better sense to use the more disorienting alterating version for it's proclaimed "tactical" mode?
It's probably best to leave any discussion of the relative merits (such as they are) of these sorts of strobes to dedicated threads on their use - I am certainly not qualified to comment.
