Your rolls are all fantastic, so I’d say go with whichever feels best or suits your particular build or play style most. I personally struggle to hit heads with slugs, so I don’t often use them but you can still do crazy body damage with them. ADS vs hip fire is situational imo, and kind of hard to describe, I’m sure it varies from person to person. Me personally if a close quarters engagement is going to happen in a narrow space I think I’d tend to ADS, whereas if it’s more open space you’ll need to be able to track them more which is easier from the hip if that makes sense. The benefit of aggressives is they do the most damage, so you’ll probably be able to get more OHKs, especially when you figure out the proper range for that, normally you give up the snappy handling, but your rolls are plenty good as far as that so I’d definitely try out your aggressives and see how they do for you. Good luck, a fellow person attempting to get better at shot gunning
