2009 Nissan Maxima or 2009 Infiniti G37?

Which would you buy if you could? I like the Infiniti G37 more, but the only thing is it's rear wheel drive. I like the reliability of the front wheel drive in snow, water, etc.. However, I do believe they have a all wheel drive models of the G37, (something I'm not familiar with, how is the performance of all wheel drive vehicles?) The G37 has more horsepower. Which would you prefer?
