Not only does the TL-S weigh the most, but it has the lowest rated horsepower and torque. Also, both the TL-S and G35 have significantly larger interiors than the IS350. The IS350, while it does have the AT, is still porky for its size. I think the IS350 would be really nice if it went on a diet (to 3,400 lbs or so), maybe with a performance trim version, and came with a 6MT. In that case it would most definitely win the comparo.
