I really recommend spackling paste because you get a nicer finish with less coats and less sanding.
I never said gesso would give the same results as the spackling paste. I stand by my statement that gesso can be sanded, but you'll notice that I said I can't promise what type of results you'll get with gesso.
Anyway, from looking at your picture I'd say you simply need more layers of gesso, especially to fill the creases and once it's dry sand it some more. Even after one more coat of gesso, you might still need to add more coats. With the spackling paste I had to add many coats too. The paper mache doesn't create a perfectly smooth surface.
