Both are equally crappy, but better than using your hands in an emergency.
Don't get dazzled by the idea of "Military Style" or "Mil Spec". In the Army we always joked that all "Mil Spec" means is "Made by the lowest bidder".
Even the military folding E-Tools are crap that bend, come loose, and fall apart; because they're not meant to do more than dig foxholes, they're under constant repair by whichever private pissed off the sergeant most recently, and they're easily replaced when they finally fail.
For actual offroading gear you want a real full sized shovel (and axe and mattock if you have room). But I do recommend having one of these crap folding shovels in your everyday emergency roadkit, even for regular street cars. Even as they bend and flop it's still better than digging in hard earth with your fingernails. If the spade breaks clean off it's still an improvement over nothing.
Given enough time you can dig a vehicle out with a teaspoon, and this would be an improvement over that.
