Good Form is a irritating sounding but poetically clever rap track, agree to most of what you said.
Minaj isn't a monster for her lyricism alone, that's never been her true forte (though she is actually very good lyrically, just intentionally dumbs it down at times for the audience's sake). Her forte is strategy in the industry and making nearly every single track a 'hot damn' of some sort.
I can appreciate her for what she is. At no point did I actually think she was a bad artist in general while listening. I got extremely triggered the first time you talked about her "strategy in the industry" because I wanted to focus on the actual content of her music itself. I don't believe that anything outside of the crafting of music makes you good at music if you know what I mean. Within the music itself though, she shows strategy in the type of songs she makes and how she goes about them so in that sense it I can see how strategy counts as something that increases her stats as an actual artist.
Good Form is not at all my favourite Minaj song, I hate listening to it for too long it gives me a headache (and most of what you mentioned, including your favourite genres other than rap, esp. metal, come into that for me) you seem to enjoy 'hard on the brain' type of stuff and Good Form is very intricate, it sounds retarded at first and irritating but if you look past that, it's actually got very clever puns and metaphors in it.
This is more the type of Minaj I love, capable to diss while making pure ear pleasing bliss and yet still looking like the 'good one' in the dispute:
