Iggy makes better music. Azealia used to be a better rapper, but she's not anymore. The last few songs that she managed to release were horrible lyrically and flow wise. So Iggy wins in everything imo.
The one with an album. The one with singles. The one they play on the radio. The one on magazines and in award shows.
This post makes me realize how far the scales have tipped and all Azealia threw away. I predict her being dropped before her album tbh. She still has a chance to be a big success though.
