I've had no candy, but did eat 2 expresso Gu things this morning. Was the first time I ever tried anything while running. They were damn good.
Yikes! I've tried a couple different coffee flavor gels and thought they both tasted like squeezing wet coffee grounds into my mouth. (and I'm a coffee fan). For the best candy-like experience, I recommend Salted Caramel or PB Chocolate, and they both have caffeine, too!

I'm not sure that the flavor was what was good. I was so hungry when I opened the first one, anything might have been tasty. I had been pondering the taste of wet leaves for a couple of miles. I will have to try a few more flavors for sure.
Runner with a riding problem.
I don't think the Espresso Love gel tastes like coffee at all. It tastes more like caramel. One of the few I don't mind.
