Storage is pretty backwards as most of the best storage methods have the worst marketing benefits. Mason jars are used in canning because they seal super tight, for long long periods of time, without leeching anything into the product. Anything with a rubber gasket has the potential of both tainting the product as well as leaks - rubber is MUCH more porous and much less stable than metal. Really good rubber isn't terrible - it will work, but the problem is that the rubber gasket is always the most expensive part of the jar which means that it's usually the first piece for manufacturers to cheap out on. The vast majority of kilner jars I have worked with were nice jars (glass wise) with really really really bad rubber on them - fine for storing pastas for a short period of time, great for keeping marbles in, but nothing else food related.
Its kind of like wine - what keeps wine better longer, a metal screw cap or a cork? Well the cork will help your product sell but it can be terrible for the wine and is the leading cause of wine going off. Of course I'd rather uncork a bottle of wine than unscrew one... Or in olive oil, what's best for your product, clear glass or dark glass - dark glass obviously but you'll sell 3 times the amount of oil if you put it in clear glass...
There is a very good reason most all jarred food is packed in mason jars, and it's not the price (for one you can create and keep a vacuum in a mason jar - wont keep for long with most kilner jars). If you have a bad mason jar lid just buy some more. You can get new lids for like 10 cents a piece... I'm not sure about those specific container store kilner jars but many many kilner jars, in addition to the rubber gasket, have an inner plastic lid that covers the glass part of the lid - spend extra on a glass lid just to cover the glass? Yum, plastic and rubber!
By no way am I saying that all kilner jars are crap or that they can't be used. They are just much much more expensive and will not keep your product any better.
If you are a big grower I would make a trip to a legit glass distributor. I can get these 1 gal jars for ~$1 a piece...
