  This is a question, one cannot answer.
  There are simply many many checkmates possible in 10 halfmoves and of course much more positions, which are dead lost.
  
  So is an opening now worse, if there are somehow 20 checkmates posssible, when comparing to another opening, where only 5 checkmates are possible?
  
  If we are taking first moves, it is f3 and g4 (only possibilities for mate in 4 halfmoves.
