To those that have cats, what cat food do you use?

I have 2 fairly new cats and one had been a feral kitten that I adopted. Both of them are pickier than I can believe. A hungry cat will eat most anything, right? Not these two. I have tried multiple brands of canned food and Meow mix, Purina One, Fancy feast, dry and can, Kit & Kaboodle, and a couple of off brands. Even the feral cat's feral mother won't touch a couple of them and she is far from picky. It almost has come to the point where I have to put tuna juice when I make tuna salads, or canned gravy to get the finicky things to eat. Any ideas?
