As per our own experience, we have not found Borosil baking dish (glass) good for baking. They are too thick and we have seen that the cake or any other stuff that you bake does not bake well from the bottom portion. Basically, the portion which is hidden deep inside the utensil would not bake well. It is advisable to use other bake-ware made with aluminum or steel with thin skin. This helps in baking the stuff evenly on all sides.
