I also enjoy doing both. I learned to crochet from books as a teenager and then in my 30's taught myself to knit from a howto book. I have developed my own style of holding the knitting needles, but I figure as long as the project turns out as planned I won't worry about it. After so many years I find that trying to knit properly is too slow and tedious and I revert back to my own way.
I enjoy both equally and it just depends on what I want to make and what materials I have available.
