Which digital camera is better...out of this 3!?

I have not used Panasonic or Casio cameras but I have used some of their other products- not impressed. They don't seem to build reliable products, at least with my experience. I am on my second Sony camera (the 1st didn't break, I just upgraded) and haven't had any problems yet. I'm pretty sure my mom has the Sony model your looking at, just the previous years model and she loves it.
