Endurolytes have saved my legs so many times I can't count. Hammer Gel takes some getting used to, some of the flavors are a little hard to get down. I don't handle real food very well on long rides so I tend to stick to the gels.
Even when I ride supported centuries I avoid all foods at the stops.I stop long enough to get water and then I'm back on the bike. I have seen too many people just sticking their hands in the fruit and whatever that it just freaks me out.
