LoL . . .this discussion comes up pretty often.
I learned to crochet first. What I love about crochet is the simplicity. You need a hook and you need yarn. I appreciate the durability of crocheted things and I also like the fact that there is much more room for mistakes so I'm much more adventurous and creative. I love to crochet things like blankets and also use finer weight yarns to make clothes for babies and children because they will be laundered more frequently. Bags and hats are also faves of mine for crochet.
With knitting, you need a lot of implements. Want to make a hat or socks? You need DPNs. What about a sweater knitted in the round? You need circulars. You cold learn magic loop and cut down on the need but that can be fussy. And, oh good grief, there is nothing worse than needing to frog something back a few rows. Live stitches strike fear and dread in my heart and I don't seem to be able to (correctly) follow any methods for frogging that would avoid live stitches. So, I'm very afraid to make mistakes (and therefore experiment) in knitting. That being said, I really like the way knitted garments look . . . to me, the stitches for knitting are more "delicate" if you will and so clothes accomodate the curves of a body better. Plus, knitted things are a lot more stretchy and have more give which I think makes that craft better suited to clothing.
As you can see, I love both disciplines and frequently combine the two.
