The thing is, you can't really engineer against anti-social behavior. For every better made apartment you will find that there is an even bigger anti-social idiot who still manages to make life hell for their neighbors.

I'm pretty blessed with my mostly boomer neighbors (🤞) who don't make a peep after 10PM, but my girlfriend has had some shitty neighbors even though her apartment is pretty well made. Sound insulation between apartments is no match for cigarette and marijuana smoke wafting in from the balcony below any time you want to open the window to air out, or if, heavens forbid, you want to sleep with the window open in the summer, nor does it help much if they are partying and speaking loudly on their balcony until 4AM on weekdays. And then I'm not even getting into how they're treating shared spaces.

The proximity makes everything so much worse than it would be with a house, at some point only adding distance helps.
