Pretty much. SPAM has more fats, which is good in long term storage foods, but it's marginal. I've tried that brand but didn't care for the taste or texture. Too much like baby food meat sticks/vienna sausage for my taste.This is the one I usually buy and prefer taste wise. I think the macros are pretty similar to the SPAM brand product. $1.98 right now.
Storing what tastes best to you is an important factor and plays a big part in the mental aspect of a survival scenario.
