Where can I save the most money but still have fun? Abu Dhabi or Al Ain?

Sorry to keep bothering people about these types of questions....but I have school spots for my daughter in both cities(I need to put a deposit down to fully secure it now), and I would love some answers on this. I have a great friend in AD that would be great, but at the same time, Al Ain has a nice quiet, family atmosphere. Plus the tuition is less that AD. Still, my good friend is in AD, and though it is not too far away by car, I think I wouldn't see her so much once I got settled in. Please advise! Thank you!
