These products both taste good and give good calories. That said, it's important to look at the ingredients:
Organic Brown Rice Syrup, Organic Evaporated Cane Juice, Organic Brown Rice Syrup Solids, Pectin, Citric Acid, Natural Flavor, Colored With Turmeric, Coconut Oil, Carnauba Wax
SUGAR, CORN SYRUP, CONTAINS 2% OR LESS OF THE FOLLOWING: NATURAL FLAVOR, THIAMINE HYDROCHLORIDE (VITAMIN B1), RIBOFLAVIN (VITAMIN B2), NIACINAMIDE (VITAMIN B3), ASCORBIC ACID (VITAMIN C), CITRIC ACID, CITRUS PECTIN, POTASSIUM CITRATE, SODIUM CITRATE, SODIUM LACTATE, YELLOW 6, BEESWAX, CARNAUBA WAX, CONFECTIONER'S GLAZE, SALT.
Neither product do anything in the category of complex carbs- this is where the maltodextrin found in Gu and other products makes them superior for hiking.
While the main ingredients of the Bloks are brown rice syrup and evaported cane juice, it's sugar and corn syrup in the Sport Beans. Much more refined sugars in the latter. In other words, Sport Beans are little more than very expensive candy. However, both do have electrolytes- something that candy doesn't.
One thing really cool about Bloks (and beans too, I suppose) is that they stay soft when it's really cold- something that bars and gels rarely do.
I'd give Bloks a 4 and Beans a 2. Average of a 3.
