we also had the same situation before (i.e. looking for a FAMILY sedan) and though the Mazda6 was considered, para sa amin ay masyadong sporty ito to satisfy our requirements for a family sedan (i.e. space, comfortable ride, fuel economy). our short list was trimmed between the camry and the sonata and after a series of test drives with the family and a lot of pencil pushing, we ended up with the 3.3 V6 sonata, only because we got it at about $500 cheaper than the well equipped Corolla S (Yes, cheaper than a Corolla).
so, if you're torn just between the mazda 6 & the camry, i suggest you choose based on your primary purpose (i.e. to be used as a family sedan), of which my vote goes to the camry.
