Matrix Shell vs Butter on

I'm pretty new to props and I'm in the middle of making my first ever helmet. After reading some of the threads I was wondering why most (when casting a helmet) choose to make a matrix shell rather than just use butter-on silicone.

Is there a reason for this? Isn't butter on easier than having to create a clay layer and then plaster/fibreglass over that - you could just paint butter on onto the helmet and then plaster over that. Or am I missing something?
