Here's my fruit ignorance. Is there a difference?

My kids gobbled up two 5 lb boxes of "Cuties" in the past two months. I loved it. They were easy to peel and everyone liked them.

I bought a different box labeled clementines and so not a hit. They look the same on the outside, but the inside was much meatier. It was harder for my 2 year old to chew. 5 year old didn't like peeling them because more skin stuck to the fruit. I thought they tasted about the same.

So did I just get a funky box of clementines or are cuties a different fruit?
