House takes the high-end route and has rich characters. Besides flirting, stories can teach you a lot.
The ratings of "House" have always been high. According to news reports, House is the most watched American TV series in the world.
The hero of House has won two consecutive Golden Globe Awards (06, 07), and the media reputation of House is far better than that of Gray.
I have seen both films. I can't watch it after one season. Now Dr. House season 7 episode 4, I have watched it three times in the first six seasons.
Actually, you might as well watch two episodes of Gray before watching Dr. House. Personally, if you are seeing a doctor, just look at the luxury equipment of House, you think Grey is really nothing to mention.
