Definitely the best. As a student, I had time to learn vim the slow, hard, purist way, and I struggled for weeks simply practicing, drilling, and tutorial-ing. Then I picked up these cheat-sheet tutorials and WOW! Just code as usual, but in vi with the first easy cheat-sheet lying in front of you; almost no productivity hit, and you seamlessly build up the cheat-sheet 'till you know all the commands! The only way to learn vim, I think.
