There is no contest between her and Wendy, except in a small number investigator game. I'd say Wendy is superior in a 1-2 player game, and sometimes in a 3 player game. Still, even in that case, not necessarily, as another way of playing Daisy is just having her search for Arcane insight and then hang out at the library to pick up tomes and spells while the other player makes sure to seal gates that will have more gates open on them. Arcane Insight used properly— even without Kate, is a huge power boost.
