Borosilicate glass handles temperature changes (such as taking something out of the freezer and microwaving it) better than the soda lime glass found in most glass containers. However, borosilicate glass also costs much more to manufacture. Corning used to make borosilicate glass but switched to soda lime glass to cut costs, then sold their Pyrex division altogether.
