Are stainless steel or glass mixing bowls better?

It depends on the task. Across the reviewers we read, stainless steel bowls are praised as lighter, nearly indestructible, and better for vigorous mixing and hand mixers, while glass (notably Pyrex) is favored for microwave, oven, and freezer use plus the ability to see contents. Many cooks own both. Community threads repeatedly note stainless lasts longest, while glass adds heat and break resistance at the cost of weight.
