tbh no. Nicki isprobably the most charted female rapper. Missyand Nicki's flow are also my favorite out of all the female rappers past and present. (there are a lot of other good ones. but in terms of success and flow i prefer Missy and Nicki)
I love Nicki and despite hating PNP and Anaconda I still have faith in her.
But until she manages to get a smash hit with a real 100% hip hop/ rap song, she's not the queen of hip hop/ rap. It's still Kim and Missy, who both got plenty of smash hits with purely rap songs. No shade, no disrespect.
