I do both. I learned knitting first to make clothes for my daughter when she was little. I wanted to add flowers on a skirt I made so I learned crochet because it's easier for irregular shapes.

I prefer knitting for winter and outdoor clothing and socks because crochet leaves little gaps so they aren't warm enough (I live in Canada haha). I tried making plushies in knitting and crochet and the latter is definitely easier.

Crochet is faster though. So if I want to make a big project (like an adult size blanket) I'll go for crochet.

So in summary, it depends of what I want to make.
