Which is better for meal prep?

The OXO set, because six sizes let you pack a full day of portions and the latch lids are leakproof for transport. The Tupperware holds one 650ml portion but vents steam, so it reheats cleanly.

Which handles higher heat?

The Tupperware, rated to 572°F and safe under the broiler. The OXO glass is oven safe to 550°F, so it is close but not broiler-rated.

Is the OXO set worth the extra money?

At its $11.88 low on November 2, 2026 it is excellent value for six containers. At $32.88 on November 6, 2026 you are paying nearly three times the Tupperware's $12.00 for one container, so wait for a lower price.

Both use borosilicate glass, but OXO buyers report chipped lips and shattering on tile, and some lids seal unevenly. The Tupperware has a 4.9 rating from 3,998 ratings with no recurring durability complaint.

Can I carry soup in either one?

The OXO set is marketed as leakproof with four locking tabs. The Tupperware lid is airtight but not sold as leakproof, so keep it upright for liquids.
