Missy's is more about herself, she sang her own songs and katy perry was just her guest for a bit.
Nicki was only a tool for Madonna herself.
I like Nicki's better even if it's minimal, because the whole GMAYL performance overall was better than what Missy did with her songs.
But Missy's cameo is better because it's actually about her, so that.
Missy. She was the sole reason why the 2015 SB halftime show was watchable.
anyway...

OP: Missy. Katy let Missy do her thing and she made Missy feel like an integral part of the show and not some accessory to cheaply get a reaction from the crowd.
