Don't think there would be a huge difference, they both have no problem taking a lot of money from people who can't afford it, and give it to people who don't really need it. More than willing to spend millions on a dream, but reluctant to spend money where it matters most. The average customer gets put on hold, until the customer service representative remembers you're there, and haven't hung in frustration, a large business or company gets someone sent over with in the hour...
I think I'd be willing to give someone like Bill a shot at running the country, or anybody who has run a successful business for that matter. Maybe Gates and Obama can get together over a beer (maybe not, Bill just got a new liver), and switch places for a few months. Doubt he could do any worse...
