NGFW + ATP vs UTM Bundle

Howdy, We are unable to get ahold of anyone in sales (or our rep at the moment) that can explain this to us so far so I was hoping someone here could help quickly. I understand what ATP is, but I am wondering if we *lose* anything if we go with a NGFW + ATP Bundle over the normal UTM Bundle. Specifically we are looking at this: FG-100D-BDL-905-36 Versus this: FG-100D-BDL-950-36 Thanks for any feedback!
