Except wasn't that the reason Nevermind got big (and subsequently why Kurt would come to hate it)? Because it was too well-produced? I mean you said it yourself. In Utero is the better album but Nevermind is the one most people associate with the band, presumably because the producer wanted to clean it up and make it sound like a pop record?
He's like "yo give me yo insurance information!" and I'm like "I didn't hit you with no car, I hit you with this mack truck I call a fist!"
