An advantage of light microscopes compared to electron microscopes is that light microscopes

The advantage i see in light microscope when compared to electron is the fact that we can view cells while they are alive and the fact that we have wider range of differential stainings for all types of cells.

In electron microscope the tissue has to be extremely thin and fixed, meaning, dead. So we cant see them like, 'while' they are dividing, we can just catch the fixed state of division. And stains have issue, its harder to deal with stains in electron microscope because of its properties in reflecting them.

These are the ones I saw as important while working in labs.
