Hmmmm. That’s a good question. Some of the E-Gel flavors (especially cherry) is too strong and sweet for my liking. I like the “mountain rush” flavor in E-Gel.
The PowerGel 4X apple flavor is pretty good- it isn’t too strong. I think a lot of it has to do with when you eat the stuff. It never fails, if you are just sitting around and taste one they are pretty bad. But when you need one bad and you are bonking they can sometimes hit the spot. It’s pretty individual.
