Bottom line
For most people, the Pyrex Freshlock set is the right starting point: glass where it counts, lids that stay attached, and shapes that stack.
Batch cooks who want a repeatable fridge system.
You need lightweight containers for commuting every day.
Container shopping gets clearer when you start with the fridge and the commute. The useful differences are stackability, seal quality, weight, cleanup, and how quickly leftovers can move from storage to reheating. For the glass-versus-plastic choice, compare Pyrex Freshlock and Rubbermaid Brilliance.

Questions, answered
Is glass better than plastic for meal prep?
Glass is easier to clean and is comfortable with hot food. Plastic is lighter. A mix usually serves a real kitchen better than picking a side.
Are Pyrex Freshlock and Rubbermaid Brilliance microwave and dishwasher safe?
Rubbermaid publishes dishwasher-, microwave-, and freezer-safe guidance for the Brilliance plastic set. Pyrex distinguishes the glass containers from their lids, so follow the current Freshlock care instructions for the exact container and lid combination.
Which set seals better for carrying lunch?
Rubbermaid publishes an airtight, leak-proof seal with secure latches and built-in vents under the latches. Freshlock uses locking lids, but the right choice still depends on the exact lid fit and how the container will travel.
What does the lighter Rubbermaid set give up?
It gives up the oven-safe glass-base path associated with the Pyrex set. Rubbermaid Brilliance is built for microwave, freezer, and dishwasher use, not for treating the plastic container as an oven dish; follow the product instructions.
How do I choose the right container size?
Start with the portions and shelves you actually use. The selected sets include multiple container shapes and sizes, so compare the published set contents with your usual leftovers, lunch bag, fridge shelf, and freezer space instead of choosing by piece count alone.
