I completely agree. In a battle between a Marth and Sheik of equal skill level, it is difficult to determine who would come out on top, seeing as how those two characters generally have contrasting fighting styles. It depends on the flow of the battle; if Sheik manages to trip Marth up (esp. with Needles) and manage to get in very close to Marth, she can easily tear him up. However, with Marth's good reach, if he can manage to keep Sheik at a medium distance, then the advantage goes to Marth. I have played as Sheik and against Sheiks, and I know from experience their capabilities up-close. But I have the same experiences with Marth (although when I fought against Marths in the tournament I entered, they were all just a bunch of counter-happy defensive players), and I know that a good Marth can do TON of damage if they keep their opponent at arm's length. In the end, it chalks up to the players' fighting stlyes and the flow of the battle.
