Where these two actually differ

- We flag Thermal shock / glass breakage risk on the Ninja and not on the Big Boss.
- The Big Boss is borosilicate glass, bare uncoated where the Ninja is Glass cooking vessel with stainless steel components, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
