Tastier than the original? For me, yes, they are!
Don't get me wrong I love a nice healthy granola bar, aka the original Clif Bar, but these are hands down my favorite energy bar! I like Honey Stinger bars a lot as well, but the chocolate coating on the Builders bars is tastier and stays on the bar better.
The texture of these things is like crunchy buncha crunch on the bottom and a smooth layer of chewy flavor on top. They don't take forever to chew and aren't rock solid in the cold.
I'll agree on an empty stomach they can lead to some slightly disgruntled intestines, but no more than a real candy bar. Definitely solid as a meal replacement for when you're too busy or need something filling.
I get a box of these every time I go grocery shopping and always have one or two in my gym bag! Try Chocolate Mint, Peanut Butter, and Lemon if you can find them!
