No style is better than the other. If you take away all the people who use DFA, backstab, backslash, it comes down to how skilled the player is. Noone who is moderately good will beat a great player with one stance vs. another.
You can say all day about how heavy sucks because all you have to do is this, this, and this, but it doesn't work all the time. If heavy stance was soooo easy to beat, I would be the lowest scoring player every time I play. All people who use heavy stance aren't "padawans" or n00bs because if they were they would be killed easily.
Just play the game...
