I have used a number of brands over the years when it comes to cookie sheets/baking pans. I always settle for what I have, but none of them really leave me feeling satisfied with the long term results. I have used Wilton's more times than not. That also includes the spring form pans for when I make cheesecakes.\n\nI am considering switching to either Williams-Sonoma, or Chicago Metallic. I have heard great things from both. More from Chicago Metallic tho. I figured I'd come here to get a few more opinions on folks that have use one or the other, or better yet, BOTH. \n\nWould anyone mind sharing their experiences?\n\nMuch appreciated.
