I think it's cause he darkens his vowls. like @minabasedjdha5972 mentioned, a lot of his inspirations are female singers, and a lot of male singers tend to brighten their voice, while most female singers (especially less "pop/rap" and more rock singers) tend to darken their vowls. Other male signers pitched up sound strange cause their voices are too bright, and if you were to pitch down a female singer she would sound strange cause her voice is too dark. For confirmation of this take a cardi B or some other rapper that has a bit of a harsher tone and try to pitch her down, it should sound pretty close to a guy singing.
