I took his, thought it and have found it to be so much easier that way than what others I know who did something different have been experiencing.
Everyone is the same this way, (kids, mom, dad) and there is a heck of a lot less explaining to when dealing with gov't, schools, etc. (Yes we're married but this is his name and this is my name and this is the name of the kids...)
One vote here for the easy way!
