I find there is a limit to how many of them I can have. The SIS Go Gels tend to make me feel nauseas after just one (60ml). I actually like the new Overstims peanut gel but I can only have a couple of those (27g) before feeling ill.
(Btw, if you think gels taste like 'man juice' then I wouldn't recommend the peanut gel as it has a salty taste... which I am told - I hasten to add in a very matter of fact, macho, manly, definitely not gay way - is how said secretion tastes.)
I prefer gels to bars (which I just don't get on with) but only use gels on long rides (3 hours plus) and then it's in the latter section of the ride. I much prefer solid foods but carrying gels is easier than carrying cake, fruit, etc and I can't guarantee there'll be a shop open to buy stuff on route.
