Which car is better Scion Tc or Nissan Altima Coupe?

I plan on buying a new car and i would like some inside information about them first. I like both the nissan altima coupe and the scion tc. I like the Altima strictly based on appearance. I've never driven it and i don't know much about it. Is it good on gas? Is it reliable? I've driven a TC and i L-O-V-E it. I like the mp3 pluggy thingy. And i hear it has the same engine as a reliable more expensive camery. I'm upgrading from a used car and all i really want is a car that i can rely on...thats kinda easy on the eyes :-)
