Is Botox or fillers better for getting rid of nasolabial folds?

As I get older, my nasolabial folds are getting deeper, so it bothers me every time I look in the mirror. I feel like my face looks so much older because of them.

So I started considering a procedure. Is Botox or fillers more commonly used to improve nasolabial folds?

Of course, I understand that the decision should be made after a hospital consultation and recommendation, but I am curious whether people choose Botox or fillers more often when both options are available.
