Video-Tutorials vs. In-Person-Classes. Does it matter ?
No. It doesn’t.
You can learn just as much from a video as you can from being there. The difference ? The kinesthetic information is missing. Truthfully ? You’re going to miss that anyway because the class is blind-leading-following-the-blind.

Physiological Control
Control is a really hard thing to get. It takes a while to have precise, or precision, control over exact foot placement, which is insanely important. It takes time to build up the necessary minute control that one needs to have over one’s body. A millimeter here, a millimeter there, cumulatively, can make all the difference between a dance that sucks (for both parties) and one that is absolutely fabulous. Precision control is where all the toys are at.
