Either application will be about 300kb (one time download). Using the applications can add up quickly. As mentioned above, BBMaps uses much less data and does a great job for point to point directions. I really like the layout of Google Maps and the simple GPS integration (the little blue moving dot is awesome).
So long as you keep an eye on your usage, 25MB should allow you to play with either application without going outside of your data bundle.
