Material matters less than most people assume; a non-slip base that keeps the bowl from spinning while you whisk one-handed makes a bigger practical difference day to day. Glass and stainless steel don't stain or hold odors the way older plastic bowls did.

Pyrex
Tempered glass bowls that are microwave and dishwasher safe and don't stain or hold odors like plastic. They're heavier and more breakable if dropped than an equivalent stainless steel set.
Anchor Hocking
Cheaper than the Pyrex set and includes lids for fridge storage, a real practical edge. Some users find the glass a bit less durable long-term than Pyrex's tempered formula.
OXO
The non-slip base is genuinely useful for one-handed whisking or hand-mixer work, and the lids seal for storage. Only three bowls in the set, versus the larger nesting counts from other brands.
Winco
Commercial-grade stainless steel bowls that won't chip, stain, or break, and they nest tightly for storage. There are no lids, and the polished bottoms can slide on a smooth counter without a damp towel underneath.
KitchenAid
A single stainless bowl with a silicone base ring that grips the counter, matching the brand of many people's stand mixer. It's sold mostly as an individual bowl rather than a nesting set, so building a full range costs more than one set purchase.
