I have maybe 60-70 or so glass food containers that get very regular use from being used for leftovers, to being put in the deep freezer for 6mo and then warmed up.

We handle at least half a dozen of these a day on average from filling/cleaning/removing portions and putting back into the fridge.

I've broken dozens of the plastic lids for them. I can't remember a single case (although I'm sure it's happened) of breaking a glass container in the past decade. They have survived more than a few rather large drops. These are the Pyrex brand glassware with the new glass that is more drop but less heat shock resistant.

Luckily Snapware also sells lids, since the glass containers far outlast the plastic lids and we end up replacing 3-4 of those a year as wear items. That doesn't bother me much since very little food gets in contact with them.

I expect my Snapware/Pyrex food storage sets to largely outlast my lifetime, but without lids to match once they stop manufacturing them.

The plastic lids always break way more quickly than the glass containers IME. Can't remember the last time I broke a glass one, actually. Plus, they actually stay in good condition. An abused plastic container will cloud, warp, gouge, and release god knows what into your food the whole time.
