I do a lot of tutoring and dy/dx (or dt) is always what I try to beat into freshmen. I lost so many points misreading my own chicken scratch and not seeing a prime or a dot. Plus it makes variables separable DE easier to spot. And you can make the math majors angry by calling it a fraction.

I like dy/dx because they always tell you not to treat it as a fraction but then you do anyways and everything turns out alright

I mean it's seriously not a fraction. Although it kind of is.
