SV != Laggy Frame Gaming
It is completely situational and optional in mapping and it does tend to look nice because it actually falls onto the middle of your receptor nicely and will give hit feedback immediately.
Most SV isn't even teleporting, just high speed or low speed notes for certain sections. When it is teleporting, it's because it's a chordjack 99% of the time (I say 99% because there's probably one or two offhand teleporting SV stream maps I wouldn't know), and even then I treat it like it's teleporting rather than "scrolling with less frames" due to immediate feedback. And then there's those times you hit an LN and all the notes slow down a lot but then the chart speeds up more than usual to catch up to where it was supposed to be and it's back to normal speed when you release at the right time. Heck, screw that, how about LN where it freezes until the release can be hit which it then teleports!
TLDR: SV is actually used in different ways. Low framerate is just... low framerate.
And even in the teleporting SV context, low framerate doesn't help teach that since SV tends to be mapped in fun and clever ways that feel satisfying to read and hit.
