Borosilicate glass has a higher proportion of silicone dioxide than Sodalime glass, Borosilicate glass does not expand as much on heating, so it is less likely to break when heated. Borosilicate glass or Pyrex is usually used for glassware that may be directly heated. Sodalime glass is sometimes used for glassware which is not likely to be directly and strongly heated.

If a glass product won't be subjected to extreme temperatures or to chemicals, sodalime glass is the cheaper and easier to work with option. If a glass product must withstand chemicals or thermal shock, borosilicate glass is the better choice.
