Honey is heavily fructose based. Fructose alone is the worst sugar option for energy gel usage (it gets complicated when mixing sugars). It’s metabolized differently than other sugars, it’s processed by your liver. In the study linked to below they measured blood sugar ratings of different sugars. Sucrose had a much faster impact on blood sugar than honey. That spike in blood sugar is what you’re looking for in an energy gel.
Maple syrup is mainly sucrose, good old table sugar. So from an effectiveness standpoint maple syrup going to do a better (faster) job as a gel than honey would.
SIS is maltodextrine based, I want to say it is metabolized even faster than sucrose, but I’m coming up empty on studies to back that up.
