I play a lot of RPGs for the story, so i take a difficulty that allows me to concentrate on the story. That said, i used to only pick easy, and for the past few years i have changed it to Normal, because i felt games were starting to feel too easy (Kingdom Hearts). But for some games i still have to go back to easy if i want to enjoy it, or complete it (Dragon Age: Origins. Easy, Mage, DON'T go into Denerim unless everything else has been done. Otherwise you find yourself caught between a boss battle and a random encounter, both of which will kill you). But as Poll said, it depends on the genre (RTS, FPS = Easy. RPG, Action/Adventure = Normal).
