On the one hand, I love all my Le Creuset. However, they were also all gifts, so I don't know for sure if I'd pay what they cost. My mom has given me a Dutch oven, stew pot, skillet, and saucepan. She has some that's over 40 years old that she still uses all the time. Even so, she looks at places like TJ Maxx to find deals on it and rarely pays retail.
The dutch oven gets used almost every day and is my go-to pot. It's just the right size for everything I do. On weekends, I might use it 2-3 times a day. I use it for soups, stews, spaghetti sauce, rice, oatmeal, hardboiled eggs, steaming vegetables, making jam, and anything else I can think of. The stew pot is good for bread and larger quantities of stews than the dutch oven will handle, and it's pretty frequent that I will use both when prepping dinner. The skillet also gets used regularly for eggs, though I prefer my 12" All-Clad skillet for most things. The saucepan rarely gets used.
