Will this connect to PC?

Yes , it will work on PC. You may want to use button mapping software as some games bug out.

Does anyone know exactly what the difference is between the regular controller and the advanced controller?

Hi. The enhanced wired controllers have two mappable advanced gaming buttons, a 3.5 mm audio jack, and more.
