I have both Eagle & Justrite safety gas cans in the 5 gallon size and prefer the Eagle can for ease of use, although the Justrite has a more durable epoxy paint finish. The safety cans are airtight and won't allow the volatile organic compounds to evaporate, nor will it allow outside moisture vapor to infiltrate.
I have never tried PRI-G but their claim that they can bring old gas back to life (which cannot be done) makes me wonder about their products, so I avoid.
