2-10, youre not gonna get a great social life with the 6-2, youre up early,be tired after, and if you go out at night for a few drinks with friends, your gonna have to be in bed by 12 and not be able to get drunk, whereas 2-10 you can still join your friends on the drink after work, get drunk and not worry about work till 2pm!
But if you needed to you could go to bed for a few hours after work anyway.
