The biggest advantage would be in the lower levels. Given a standard size party of five or six, acceding one initiative, occasionally, to the one character who
actually starts the attack seems little enough, to keep play moving, and morale up. Given, of course, that it is an unpredicted and unobvious attack, at the time.
Emphasis above added. As time constraints seem to get more numerous I find this to be of more and more importance to me.
