I don't think I have a out and out favorite... it depends on what I am cooking.
I use my 3.5 Cuisinart sauté pan quite a bit. I like the straight sides for pan frying and then making gravy. Moreso than a frying pan. Less splatter, plus you never know when you'll need a lid, but the same lid for my sauté pans also fit my Cuisinart fry pans. Still, it's easy to stir food around with the higher sides and whisk up a gravy. Chefs Classic I think they are. And I like this non-stick, kinda wok shaped pan, too. It's good for throwing a concoction together, like loaded mac and cheese, where you are frying up sausage and onions to start. It's easy to build stuff in, has lots of room, plus it cleans easy and has a lid. I don't remember the make off hand, but it's a real multi-tasker. The only thing I don't like about that pan is it's not dishwasher safe, whereas my other non-stick cookware is.
Really, anything is my favorite as long as there's food in it
