Second difference - plugin can handle resize not only window, but any container that you want and redraw without your attention
Horizontal and vertical scrolling of window or any container or both

Doesn't matter, has row colspan or not
CSS Element Queries (only if you want that plugin handle resize of any element on a page and redraw sticky header without your attention)
