I like 1920 x 1200.
The shape is more square, and you can fit a bit more detail on the monitor.
1920 x 1200 is not made so much any more. The standard TV 1080P(1920 x 1080) panels are cheaper due to higher volume production.
For desktop work, consider using two 1080P monitors, or even 2560 x 1440 monitors.
