Fruit snacks, like most modern junk food, can taste great, but you should definitely consider them in the same category as things like chocolate, something you eat for the awesome taste knowing it's not exactly that great for you. As people mentioned basically most of the fibers and other nutrients have been removed, leaving mostly just flavored fruit syrup (although they usually they add back a few good things, like pectin and a few vitamins).
Muse's suggestion of making your own sounds like a great idea, although you would still be even better eating fresh fruit, plus if you already don't like to snack on fresh fruit chances are you won't like the dry equivalent (they won't taste anything like say a fruit roll-up, you need science to make that stuff
)
An important note however, the sugar in them is not more natural than HFCS or anything else. There is no such thing as natural or unnatural fructose, it's the same molecule.
Calorie for calorie, HFCS is actually -healthier- than the sugar from a fruit snack/fruit syrup or say clear 100% apple juice because the ratio of fructose to glucose is proportionally less, where fructose is the worst of the two in terms of health consequences. A valid point can be to look at what else is present or added back to foods (for example pectin and vitamins are good to have on the side), but again other terms like natural just do not apply to nutritional molecules because identical molecules don't have any sort of memory of where they came from. The term is more meaningful only when apply to say cultivation methods, cooking methods, different varieties of foods, completely different molecules etc. For example you could make an argument for lactose having situational nutritional advantages over plain glucose because of absorption dynamics etc.
