Stainless steel, glass, or plastic — which mixing bowl material is best?

Across the reviewers we read, the answer depends on use. Stainless steel is the specialist-community favorite for general mixing: lightweight, durable, and effectively unbreakable, with r/BuyItForLife and r/AskCulinary threads repeatedly recommending 18/8 or 18/10 steel. Glass (notably Pyrex-style tempered glass) is preferred when you need oven, microwave, or freezer compatibility and don't mind the weight. Plastic and melamine sets win on price, color, lids, and dishwasher convenience, but reviewers note they can stain, warp near heat, and are not oven-safe.
