It depends what you're trying to accomplish by eating honey vs. sugar vs. maple syrup.
Technically, all three are the same basic element: sugar - a combination of sucrose and fructose to be specific.
If you're diabetic, you might do *slightly* better with honey than table sugar b/c the Glycemic Index for honey is a little bit lower than that for table sugar (87 vs. 100, I believe).
Table sugar, fwiw, is far, far better than corn syrup or especially high fructose corn syrup, which is even more refined and has a terrible effect on blood sugar levels.
If you're trying to control weight, then table sugar may be the best option because honey and maple syrup both have far more calories than plain table sugar, by weight. For example, 1 tbs. of sugar has 44 calories compared to 64 in honey, and 167 in maple syrup!!... plus some people feel honey tastes less "sweet" so they even use more honey in tea for example than they would sugar. This is a double whammy for the person trying or needing to be calorie conscious.
From a nutritional standpoint, honey probably fares best, followed by maple syrup and table sugar. But if you eat "honey bear" type honey, or any processed/heated honey like that, any of the proported nutritional benefits have been made obsolete by the processing. So if you choose honey, make sure it's raw, organic honey, otherwise, there are no nutritional benefits and all three sweeteners then become more or less equal.
Finally, there are environmental / "green" concerns to consider. Maple syrup should ONLY be organic.... there are some seriously undesirable practices in the collection and production of mainstream maple syrup, such as plugging the holes in the tree with formaldehyde pellets and using lead collection buckets

not to mention killing the trees eventually in the process. Table sugar might be even worse and gets into issues of treatment of workers, fair trade, etc. as well. Organic is the way to go if you are concerned about nutrition and environmental impact of sweeteners.
Bottom line - if you use sweeteners occasionally you could pretty much choose whatever you wanted, but I do think there's a lot of reason to choose only organic especially for the three sweeteners mentioned above.
Hope this helps!
