Majority of the "twitter barbz" are a bit petty. When Nicki first came out with PF, the barbz wanted everyone to show Nicki love and no hate. But, when Iggy releases her first album it's nothing but shade and hate. They're a bunch of hypocrites.
I'm actually glad another female rapper is out. No matter if they love Nicki or not. I was honestly excited for Azealia Banks, but......nevermind (

)
Iggy has potential to be Nicki's competition. Give her a year or 2.
I hope Angel gets better musically, so she can be in the running as well.
The New Classic is actually a really good album, and i like it better than PFRR.

Iggy's verses on I'm Coming Out & Problem are really good and i can see her going far if she plays her cards right.
And Nicki shouldn't "compete" with Iggy, because it's already been confirmed that Nicki is better than all of these new female rappers. Let Nicki compete with the males. (which she's already doing)
Let Iggy shine.
