It's a broad sweeping statement to say that one martial art is "hard" and another "soft". It depends on who's applying it. I have seen "soft" expressions of what is traditionally a "hard" martial art and vice versa.

Yin and Yang (In/Yo, hard/soft, fire/water) are 2 sides of the same coin.

Bear in mind that perhaps what one experiences in a "hard" style is simply a "beginner level" of expression and understanding of the art.
