The position of the sticks is unusual, but you quickly get used to it.
I play mainly with it in Dark Souls, it is much more convenient than with the keyboard, especially in the 1st part.
Has pros:
Comfortable, beautiful, deepening in the sticks, vibration adds more feeling to the game (unlike playing on the keyboard), support for many games, long wire.
Different cons:
D-pad uncomfortable, gets dirty quickly, RT and LT triggers are awkward to press quickly and are only suitable for racing.
