OXO Good Grips Smart Seal Glass Container Set vs Pyrex Simply Store 18-Piece Glass Food Storage Set

Buy the OXO set if you want a smaller, leakproof set that goes from freezer to a 550°F oven and cleans up in the dishwasher. Buy the Pyrex 18-piece set if you want more containers and larger bowls for batch cooking and fridge storage. OXO's borosilicate glass and four-tab Smart Seal lids draw consistent praise for tight seals and sturdy build, though some owners report lids that leak and glass that chips or shatters when dropped. Pyrex gives you more pieces and bigger bowls, but its lids are not leakproof for travel and the glass is soda-lime, so it handles oven heat less well than borosilicate.

• Choose the OXO Smart Seal set if you pack lunches, carry food, or want leakproof containers that move from freezer to oven without a transfer.
• Choose the Pyrex Simply Store 18-piece set if you mostly store and reheat food at home and want more containers and larger bowls for the same shelf space.
