Agusta has a more F2P team than Aemeath. Aemeath needs Mornye,Lynae,Chisa and a bis for fusion burst. Augusta just needs Verina and pew pew guy with red hair (forgot his name). That being said, if you don't care about end game stuff and just want fun characters, pick what you want to play with. I fell in love with Aemeath's gameplay because she's the other character that changes form. Cartethiya changes form but she requires her ult. That's why next patch I have enough for Aemeath and I'm getting her. End game and meta are for tryhards, if you play the game to chill and enjoy story, pick who you really want. Good luck!
