Personally I like the Datrex better than everything else I've tried. It's kind of embarrassing how much I like them given that I'm a chef! blush grin Like most of those types of rations they're not very good for you/healthy for long term use nor are they intended to be- they're survival food. But if they weren't so carby I could eat a block of them every day.
