Knifty Knitter or knitting needles?

I have a small amount of crochet and knitting experience. I would like to make my daughter a hat, scarf, and mitten set. Should I just try to concentrate on knitting or crocheting them...or should I try knitting looms? I don't know if the looms are worth trying or if I'd feel better if I stuck with what I already know. I don't want to have to spend a lot of money on new tools and book for instructions.
