A non-stick pan is what you use if you're cooking foods that tend to stick.

The geometry of a pan can affect how easily moisture is driven off of food, and how rapidly a sauce will reduce. It's often claimed that the sloped sides of a skillet help moisture exuded by cooking meats evaporate more rapidly, allowing you to sear more efficiently. And this is true, but only given the same cooking area. In other words, a 12-inch skillet with a 10-inch cooking area will sear foods more efficiently than a 10-inch sauté pan. The corollary to this, of course, is that, given an equal amount of food that needs searing over super-high heat (some steaks, for example), the large surface area of a sauté pan does not offer any significant advantages over a skillet—you'll still have to cook in just as many batches.

Faster Cooking Times: The application of a bacon press or steak weight can help reduce cooking times by ensuring that heat is evenly distributed and that the meat is in full contact with the cooking surface, leading to more efficient and consistent cooking.

Is a skillet better than a frying pan? Which one should I choose?

Skillets can be made from different types of material. Stainless steel, aluminum, and cast iron are common options. Some skillets are made from a combination of aluminum and stainless steel. Aluminum pans that have a thin gauge (read: not very thick) aren't the best choice since they are more likely to warp.

Nowadays, “French skillet” refers to the specific design aspects of the cookware rather than its place of origin.

Typically made by adding a non-stick coating to aluminum pans, non-stick frying pans are ideal for cooking delicate foods with a tendency to stick, such as fish, fried eggs, and pancakes. The non-stick coating limits the amount of oils and fats needed to cook food and makes cleanup a breeze since your food won't stick to the pan. Non-stick pans are best used in low to medium heat settings to extend the coating's life. Using a non-stick pan in high-heat applications can damage the coating and cause it to smoke, peel, or flake.
