Well, you'll feel the biggest need of range if you do any wildlife photography. You almost always feel the need for more range there. Also make sure to consider your lighting conditions. Since neither lens is very fast, you'll either have to shoot in bright conditions, use a tripod, or you'll have an increased need for the IS of the Canon. The IS will likely have a decent impact on the amount of keepers you get when shooting slower speeds with the Canon, especially because it's a tele and vibrations from your hand are magnified as your lens gets more reach.
Also, how much macro do you really think you'll be doing, and how high of magnification are you looking for?
If you're looking to mess around with macro, I personally think the easiest way to achieve decent quality and high magnification on a budget is to get some extension tubes and an old cheap manual focus 50mm 1.8. The 50mm 1.8 is usually a very sharp lens, and you'll be using manual focus/moving your camera in/out in macro anyway, so that isn't a concern. |
