Does cookware make a difference for you?

I have a pie pan from Williams Sonoma that I love. The pie crust always seems to come out perfectly when I use it. Is it luck, or is it the pan? I've also used the pie pans from Marie Calender, but I'm embarrassed to use them because someone might think I bought the pie there instead of making it like I said.

I spent a bit of cash on All-Clad pots and pans, but I don't know if they'll be good as I get older. They're so heavy.
