It depends on the game. Monkey Ball: Easy, because I play through all the difficulties one after another (different levels), Mario Kart: 150cc (so hard), because everything slower is too slow, Uncharted: Started it on easy and would have changed to very easy if it was the PS4 version, because it is a shit game and difficulty just changes how much of a bullet sponges the enemies are. Basically the rule of thumb is: If I think the game is good, I like to have a challenge, but if it is a garbage game, I'll gladly take easy mode.
