Which do you prefer, knitting or crocheting and why?

It's probably bad that this gets the same answer as most of the sex questions.. "Depends what I'm doing...."

Crocheting is faster, so if I'm being impatient or need something done quickly I appreciate it more. But it also uses half again as much yarn as knitting AND the patterns aren't interchangeable.

Knitting uses less yarn and often has a more "polished" look to it, but takes longer.

Have at it.
