Infiniti G37 vs. Lexus IS 250, I'm looking for reliability and longevity.?

I'm having trouble deciding between these two cars and i want to know which car has the best reliability and longevity, i'm looking to keep this car for at least 10 years. Which one is best on gas mileage and which one would have better traction with wet weather because i live in a city where it rains hard quite a few times a year?
