I also like the several Pyrex/Borofloat/Duran glass-bottomed ones with plastic lock on lids with a sealing gasket that I have tried. I now have three that I bought here in Sweden at various places over the last 5 years which are more-or-less the same shape and size. The lids aren't interchangeable due to them being from different manufacturers. I have a few others from the same manufacturers, but they're bigger and haven't made any treks by bicycle.

I find that if I pack them when everything is hot, the air gap shrinks volumetrically as it cools, and it helps keep everything under vacuum in a way. Often if I want to open them directly from the fridge I need to pry the edge up with a knife, actually, to release the relatively small level of vacuum before I can open them.

I was trained with good industrial hygiene and safety, so I always have them secondarily contained in another thing like a ziplock bag, which can be re-used many times without a leak. I understand that if I'm in an accident, the bag may rupture. I'm okay with the risk of needing to buy new socks and the potential release of 0,5 liters of chicken broth in a small radius surrounding my corpse.

I only have one bottom and lid from the IKEA stuff, but I like them as well as the others and the idea is perhaps better. One can buy the bottoms and lids separately, and many of the sizes mix-and-match, along with the plastic bottomed ones. If something goes wrong, you don't necessarily need to buy all the parts together again, and perhaps you don't need so many lids in your collection.
