Which is better for meal prep?

The PlanetGoods set gives you three containers at once, which suits batch prep. The Tupperware Mini is better for single portions and reheating in the oven.

Can the Tupperware go in the oven and the PlanetGoods not?

The Tupperware is rated oven and broiler safe to 572°F. PlanetGoods only states freezer, microwave and dishwasher safe, so keep it out of the oven.

Which has the better lid?

The Tupperware easy-press lid is airtight and has a steam vent. PlanetGoods buyers report the glass lid is hard to seal tightly.

Is the PlanetGoods set worth $34.97?

That is about $11.66 per container, close to the $12.00 Tupperware Mini. You trade oven safety and lid reliability for three stackable square containers.

Both use borosilicate glass, so the containers should hold up similarly. The Tupperware lid design has the stronger track record across 3,998 ratings.
