I think the most satisfying part for is the elimination of the constant context switch between my jsx/html and css file.
We use CSS modules and it drives me crazy to keep switching back and forth to add styles.
Plus is think <div className="mx-12 lg:mx-24 md:mx-12 bg:white dark-mode-bg:black />
looks just outright readable and tells me everything i need to know about that div in one glance.
I for one absolutely love it, but have team members little on the backfoot. Preferences i guess
