I must put out the idea of a Ford Flex...it has 3 rows and is a bit less bland than many other van type vehicles.
However from the two options I would probably opt for the Town and Country...the Mazda 5 is far too reminiscent of a Prius I suffered with as a rental. I will say that many of the Dodge/Chrysler/etc vehicles I have owned and driven lately are actually of much better quality and build than they were several years ago. Many of my friends own Dodge vehicles, my mother just bought a 300C and I am a loyal Jeep fan...no issues with any of them so far.
