If you're just starting out, I'd suggest you get a hidden-tang knife. I started out with a prejudice that "full-tang=better," and have two sirupatis with both types of handle.
I'm being won around to the hidden tang. Part of the reason is that, after handling both knives, I'm pretty well convinced they will both see me into the ground. I doubt the difference in strength means anything in human terms, and the chiruwa tang does add weight.
Also, I'm not sure the chiruwa tang changes LATERAL strength that much, but somebody with more engineering brains would know better than me.
