The speed and temperature of the cooking, along with the liquid used, should help with your decision. Those slow-cooking recipes for sauces and liquid broths will benefit from a saute pan's depth and large surface. For those recipes that need meat grilled or seared at high heat, you might want to consider a frying pan. The sloped side of the skillet also makes it a great candidate for stir fry. But if you want to achieve the perfect finish for stir fry, a wok would be the best choice.

The quick answer is, no. A skillet and frying pan are different because of each’s cooking surface and design. There is often confusion because the terms “skillet” and “frying pan” are often used interchangeably. And you can typically use either one of them for many cooking preparations, even if one is better suited for a specific cooking method. Plus, both of these style pans are often made from the same materials and come in similar sizes, so it's easy to understand why there can be confusion. While similar, a skillet is technically a bit deeper and has a slightly larger cooking surface area than a frying pan. 

While saute pans are designed to retain moisture and help steam vegetables, French skillets are better suited for frying and cooking dishes that require larger surface areas.

When a chef cooks, the quality of the dish is determined by more than just the recipe or the chef's expertise. The cookware used plays an important role in the quality of the taste too.
