Mick Jagger is of course a really charismatic and phantastic guy, but I would vote for Jim Morrison because he is really a FRONTMAN - the rest of the band
is rather invisible.. more or less. MJ is nothing without Keith, the interaction between them both was and is awesome and that's what makes Mick a great singer. But for a FRONTMAN, I would go for Jim Morrison or even a certain Mark Knopfler...
But this whole type of poll is uninteresting, every one on that list is/was great on his very own way..

The greatest frontman of AMIT is POTTEL anyway... whereas of course the finest FRONTWOMAN has to be the president of course...
