Since then many more have been made and we have the best use of light there ever was today.

Incandescent light bulbs have been around for so long, because they work and are cheap. They do the job, but are it most efficient. For most people though efficient is not their main concern. Therefore, today there is still a large variety of the light bulbs that are purchased and which of them is their preference.
