This. Being a slow writer, it was a constant struggle for me through out school & college to keep pace with the instructors. I can imagine the same problem for the instructor as well - you need to be reasonably legible and fast to be able to cover everything.

On the other hand, I have often found PowerPoint based presentations to be boring and uninspiring. I remember a class on Thermodynamics from college that I found so boring for this reason that I nearly flunked it.

The best classes I have taken have been once which are primarily PowerPoint based with instructor jumping onto a whiteboard to flesh something out as required. PowerPoint provides the peace of mind that it will all be available if I need to refer to it later and working on whiteboard brings in the engagement and chance to go off track in between.
