Ptosis surgery for a drooping eyelid really worth it?

It depends on you.: Ptosis repair is indicated medically to improve your vision. It can also make you look better. If any of these things are bothering you, then it might be worth it.

That depends...: On how much it bothers you. It is important to be properly informed of the risks & benefits by your surgeon, so you can make an informed decision. Things to consider: how much does the obstructed vision affect your daily activities (reading, driving, etc.)? Do you maintain a chin up posture to see? Eye fatigue? These can be improved with surgery but there is a risk of dryness, asymmetry &revision.
