The difference in performance benefits from different energy gels is probably too small to notice. What I do notice is the flavor and how easy a gel is to digest. The Honey Stinger gels all taste pretty good, some, like the Strawberry-Kiwi, have a slight caffeine taste, which is obviously absent in the non-caffeinated flavors. I sometimes have digestion issues with maltodextrin, which is not an ingredient in the Honey Stinger Organic gels, but is a common ingredient in others. At the very least, it's nice to have a variety.
Honey Stinger is my go-to on-bike nutrition gel. It stows easily in a jersey pocket. It is easy to open and eat while on the road, provides a very quick energy boost, and helps fight off muscle cramps and fatigue. And because it is honey-based, it digests quickly without causing any GI distress. No more burping up the gel while I'm riding. It is the best-performing on-bike nutrition gel I've found.
