If we're comparing as a whole two lines yes. You can't really beat getting an artist that can sell 10 Wembley Stadiums out though, is say that's probably the biggest booking except for Taylor Swift the festival can make.
Sub wise Glas this year was bad at it gets and even with Cave, Paramore and Charli would be better. I would Dua Lipa, Coldplay and Olivia would be my mix of the top line there quite comfortably.
