The Storm is very well made, and has excellent ergonomics; but the blade has a very thin hollow grind, and the handle is very thin as well.
The Buck has a thicker (if somewhat less sexy) blade,and a *much* thicker handle.
If you want something that carries easy in your front pocket, looks good in your hand, and isn't gonna be used hard, the Storm is a lotta knife for the money. But if you want something sturdier, more comfortable in extended or hard use, and don't mind carrying it in a belt sheath, the Buck is a much more rugged piece of hardware.
