The airbake did bake differently because of the double layer of metal with the air pocket between them. The airbake would allow you to overcook the items without excessive browning or burning. You could produce a beautifully browned cookie that was hard as a rock if you weren't careful
There is a learning curve with these.
I use that airbake pan plus I have a jellyroll pan that I also use for cookies. I never had a learning curve with them and have never had cookies turn hard as rocks, but I do watch my cookies very closely. My daughter-in-law asked me why my cookies never get dark on the bottom, so when they moved into the new house I bought her the airbake pans I have. My 5 year old grandson loves to bake cookies with mommy and he is happy that the cookies turn out like grandma's.
