I like Fig Newtons as a snack/treat (also the berry versions). Not sure I'd want them as a primary fuel source during rides though, as the fiber/whole-grain content might cause stomach unpleasantness especially if eating a lot of them. But if they don't bother you, I don't see a problem.
For more casual supported rides with rest stops, I'll munch on solids when we stop (usually some sort of cookies if available). But while riding (and especially while racing) I stick to mostly liquid calories, supplemented with gels if needed for longer rides. The Hammer Gel flask is convenient since it holds several gel packets' worth and you don't have to mess with opening wrappers while riding 25+ in a crowded field of racers.
