Yay, I love this debate! I call it German knitting because my German grandmother taught me- but it is also called Continental knitting. I know both German/Continental and English/American methods make equal results in the end, but since I originally learned to crochet first (and I am right-handed), I found the transition to German knitting easier because I was holding the yarn the same way with my left hand. So if you have done crochet first, you may find that German or Continental knitting may be easier for you to do since you are used to holding tension on the yarn in the same way.
Just my two cents, but I hope it may help you in your decision.
