The biggest difference is that with House Dance you can still listen to the song if you turn off the screen. With social rock you have to smash the speakers.
House dancers have absorbed the styles of poppin, locking, hiphop and so on, but due to the lack of innate conditions, the basic skills are not hard, most enthusiasts have only learned the skin. Of course, the nerd dance circle also includes some very nerdy professional dancers who have received formal dance training and have a high level of skill.
The social rock, presumably, was thrilled by watching jazz and imitated it without any rules.
Social rock music is trashy and one-dimensional, with one-dimensional moves that are even less technical than those bad otaku dances.
