There are so many different pans on the market today that it's unreal. I've never seen the Wolfgang Puck pans, but I can give you some pointers for what to look for.
--purchase a heavy grade aluminum pan--one that is thick not only on the bottom, but also on the sides of the pan.
--other options, such as stay-cool handles and glass lids can really make cooking easier...so consider these options as well.
--look for a product warranty of no less than 1 year--5 years replacement is optimal.
--surfaces such as teflon can enhance your cleaning ability, but can also be hazardous if you have small pets (such as birds) in the house. There are other non-stick surfaces that are stronger the more durable out on the market these days that are safe for use with metal utensils.
Having said that, I think there are different pans that make the grade for each type of cooking you do. For sauteeing, I would pick a heavy aluminum pan with a non-stick surface. Aluminum is the best conductor of heat. Stainless steel is the least pourous and does not react with high-acid foods like tomatos, so perhaps a stainless steel 6 qt. pot with an aluminum core would be best for your soups and stocks. A pan with a stainless steel strainer is GREAT for cooking spaghetti and other pasta noodles.
Cast iron pans (like those offered by Le Creuset) are also great for cooking sauces and stocks--as they will hold heat longer than aluminum.
I am quite the fan of
Amazon's open-stock pot selection for this reason. Although it would be nice to have a new set of cookware that looks pretty hanging from the potrack, I would rather have a mixture of pans that are best for each use.
Good luck on your purchase!
