Lovely, get one. Maybe a 9 inch round. It is amazing that the difference is so pronounced.
I did a test on Wilton, Williams_Sonoma regular, and WS Goldtouch cupcake pans. I made one batch, used the same oven and same liners. I could see the difference even between the great regular WS pans and the Goldtouch. They really are amazing and I beat them up with the sugar work.
For my bakery, I have invested, a little at a time, in multiples. On brownies and other items I put in 13x9 pans, with strips, I never have to waste the edges because they got too hard.
