In my experience, that pitted look (the orange peel finish) actually helps to create a sort of non-stick effect. completely smoothing the surface is a mistake.
I've heard and read others with widely varied opinions on that subject. One thing is undeniable though; the current rougher finish is indeed because it's cheaper to produce; the product is gravel washed by machine rather than hand finished as the old ones were back in the day. Hence my recommendation for the Wagners and Griswolds brands of an earlier era.
My own experience with the smooth finished ones is limited to back in my teen years while still living at home and using my grandparents' CI (all smooth finished) Yes, it was much better but I have no idea if it was because of that smooth finish or simply decades of seasoning?
