It's the specific components and the ways they're combined that create different frozen confections. There's one for just about every taste, mood, health concern and budget.
Ice cream -- By United States Department of Agriculture (USDA) standards, a food labeled "ice cream" should have at least 20 percent milk solids and 10 percent milk fat by weight. Premium brands are fattier, typically 14 to 18 percent. Both milk and cream are used. Sweeteners account for another 15 percent or so.
Frozen custard -- A touch of egg yolk is what distinguishes frozen custard from commercial ice cream. Legally, custard only has to contain 1.4 percent egg yolk by weight, but some brands have more. The lecithin in the yolk is a natural emulsifier, imparting a richer, creamier texture.
Gelato -- Gelato hails from Italy, and its name is simply the Italian word for "frozen." Gelato traditionally is made using mostly or entirely milk. Having little or no cream reduces fat while intensifying flavors. Gelato's melt-in-the-mouth creaminess comes from sheer density: It's churned with relatively little added air.
Frozen yogurt -- Frozen yogurt blends yogurt (milk fermented with yogurt cultures) with an ice cream base of milk, cream and sweetener. The resulting dessert is both sweet and tangy, cold and creamy. If made with live cultures, frozen yogurt promotes digestive health by encouraging the growth of "friendly" bacteria in the intestinal tract.

I've always been confused about this - what exactly is the difference?

Also, why do people say that Frozen Yogurt is better than ice cream?

I know there's something about "probiotics" with fro-yo...but after all the processing and artificial sweetener I don't see how it's any better than regular ice cream.

Some people say that fro-yo is better because it doesn't have as much fat/is nonfat...but I don't see why that makes it "Better" than ice cream. Some kinds of fro yo may have less calories...but won't the fat in the ice cream be better in the end, since it will make you more full? And they both pretty much have the same sugar count, so...

Do any of yall have a preference one way or the other, or know about the nutritional value and benefits of one or the other? Thanks so much!

Depends on the brand and the ingredients, here in the UK we have ice cream that is air whipped with artificial chemicals so that it's low calorie per ml but gives even nice kids behavioural problems, and ice cream that is wall to wall saturated animal fats and added sugars so obesity or a heart attack in a bowl.
