Out of those, I would go with the Giant Escape model.
Now is it worth buying an Escape 2 over the Escape 3. Escape 2 has an aluminum fork and Escape 3 has chromoly steel. Escape 2 is a 8 speed bike and Escape 3 is 7 speed. The only 2 major different.
Try them both at the store and see which one is more to your liking and needs.
