Which is better for pressure canning?

The FORJARS set. It is rated for pressure canning and water-bath canning with thicker glass. The Mainstays listing markets home canning but states no pressure-canning rating.

Can I freeze or microwave either jar?

FORJARS states freezer safe and microwave safe. Mainstays does not state either, so use those jars for fridge and pantry storage instead.

Which has better reviews?

FORJARS scores higher at 4.9 out of 5 from 600 ratings. Mainstays has far more reviews, 1,535, at 4.6 out of 5.

Are the lids dishwasher safe?

FORJARS describes its lids as rust-resistant and the set as dishwasher safe. Mainstays says jars are dishwasher safe but lids and bands are hand wash only.

Is the FORJARS set worth the extra?

If you pressure can or freeze in the jar, yes: thicker glass and rust-resistant lids matter there. For jams, oats and pantry storage, the Mainstays pint jars do the job for less.

Do the Mainstays jars have measurement marks?

Yes. The glass has embossed measurement markings, which helps fill to a level and portion consistently. FORJARS does not mention markings.
