1st reason:
The overlay handling.
- some support programs work better with border-less window like - Steam popups from firends or Fraps.
Fullscreen uses less video RAM and dedicated access to gr. card ->> the game has better performance.
2nd reason
in case of two monitors behavour is different.
- True fullscreen - mouse cursor doesnt go away from the monitor.
- Border less window - you can freely/seemlesly move your cursor from one monitor to another.
It depends what you want to do.
In case you do some guide (or are you skype chatting on other moitor) you might prefer Border less window.
In case you watch a movie on the second monitor, you might prefer fullscreen to prevent unwanted moves out of game.
Alt-Tab works the same in both cases.
