OXO Smart Seal Glass Container vs Pyrex Glass Storage with Glass Lids 10-Piece Set

Buy the OXO Smart Seal if you want a leakproof, oven-safe glass set with interchangeable lids and four locking tabs. Buy the Pyrex 10-piece set if you want more containers for basic fridge and microwave storage. OXO's borosilicate glass handles thermal shock and its gasket seal holds up in bags and stacked fridges; Pyrex's tempered glass is tough but its lids are the weak point. Owners of both praise the glass for not staining or holding odors; Pyrex buyers more often report lid cracks and lost seals.

• Choose the OXO Smart Seal if you pack lunches, marinate, or carry food in a bag and need a seal that won't leak.
• Choose the Pyrex 10-piece set if you mainly store leftovers at home and want more containers in mixed sizes.
