Ignore the piece count until you unpack it
The more useful comparison is mixed sizes versus equal small sizes. Nest Lock includes capacities from 230 milliliters to three liters. The selected OXO set repeats a one-cup size four times. One suits a changing collection of leftovers; the other suits several similar small portions, dips or prepared ingredients.
Match storage to what comes off the stove
A few spoonfuls of sauce and the remainder of a large soup batch rarely need the same container. A range of sizes can reduce the habit of using a very large box for a small amount of food. Nest Lock makes sense if those different amounts regularly arrive in your fridge on the same evening.
Equal containers become useful when you portion the same quantity repeatedly. The OXO set avoids searching through several sizes for the fourth matching small dish. Its one-cup capacity remains a limit, though. If your usual lunch includes a substantial serving of grains and vegetables, determine the volume before assuming a small glass pot is a complete lunch box.
Check how the container will be reheated
Joseph Joseph permits microwave reheating under its instructions and specifically excludes ovens and grills. It says to remove the lid and place it loosely on top rather than fastening it shut. That is a practical distinction if leftovers are usually reheated quickly in the same storage container.
OXO documents oven, freezer and microwave compatibility for the glass bodies. Follow the product instructions for heat changes and remove or position lids as directed; a plastic lid does not inherit the body's oven use. Follow the temperature limits and heating instructions for the exact container.
Plan the empty cupboard as well
Nest Lock's bodies nest and its color-coded lids snap together, which can help when several sizes need to live in one cupboard. Keep the matching system intact by drying pieces before stacking them. OXO's removable silicone gaskets allow access for cleaning, with more individual parts to keep track of during washing.
Choose Nest Lock for its range of volumes and documented nesting arrangement. Choose this OXO set for four equal small glass containers. Both need a washing and drying routine that includes the seals. Buying the right sizes for your actual food is more useful than adding a large set that simply replaces a crowded drawer with a differently crowded drawer.
