They are 20 gauge SS which is ~0.9mm thick as opposed to the 1.2mm thick megapots. That is a pretty sizable quality difference. That being said I am sure the Bayou would work just fine.
Side note: 11 gallons is too small for a full volume 10g boil IMHO.
Side side note: a have seen some very nice pots for excellent deals at outlet stores like Marshalls, etc.
