text: As having a great knowledge and interests in animals native to the North American continent I've heard of more Bull Moose attacks,  but don't get me wrong when Bull Elk range off into urban environments humans pose a threat to the animal and the animal defends itself.  The same goes for any Bull Moose.  If you show your scared or you threaten them they may attack, any deer in the related family will act the same way.  Thats why hunters take more precautions when trying to successfully bag the big one.  I honestly would never want to mess with either of the two large animals.   The most dangerous in my opinion would have to be prized to the Bull Moose.  But,  its your call.  Have you been out in the field with these animals?  Maybe not.  It looks to me as an adrenalin rush,  a run for your money.  I hope I've helped you.
