Frog sig is 39% better (which is a lot but it has become the norm since Cart) but she clears endgame just fine.
Augusta sig is the same but her team does so much damage it doesn't matter.
The catch is you want good team or else you will struggle. Cart without CIA or Frog without Cantarella is kinda ass. Still Frog and Augusta is quite versatile unlike Feeb, Zani and Cart.
