PowerBars provide a balanced source of protein, but won't replentish the fat you consume. PowerBars also tout vitamin fortification, which is of questionable value over a multiple vitamin supplement, aside from replacing electrolytes.

PowerBars are fairly expensive, and the while they doesn't include information comparing simple and complex carbohydrates, it doesn't look good given fructose syrup as the first ingredient. Powerbars tend to lose on taste, especially when eating large numbers of them. They are durable, but get quite hard at low temperatures.

Given this comparison, the best bet seems to be the least expensive option, provided that you include some supplemental protein in your diet, such as a protein-rich sport drink, some of which are reviewed in another article. Another good source of protein and fats is peanut butter in sandwitches or in home-made energy bars.

Home-made energy foods may indeed be your best choice. Several recipes for home-made energy bars are available, which are generally better-tasting and more nutritionally sound, if lacking vitamin fortification gimmicks.
