The only real advantage is that it leaks slightly less slowly. But because it leaks more slowly that leads you to be lazy in checking your tire pressure. Pressure change in response to ambient temperature is roughly the same. Interior oxidation is a non-issue, exterior UV is far more harmful than O2.
Just check your pressures once a month or more and you'll be fine. Wish they had left the tire pressure display screen, even a $20K Chevy has that now.
