Cardio or Crossfit?

I would go CrossFit so you can loose weight while also lifting and getting bigger muscle wise.  5'7"/160 is not that overweight, plus you don't want to cardio to the point where you're a thin dude with no muscle at all.

It's all about calories in, calories out. If you eat right and track your calories both options will suit you fine.

are you trying to cut weight for a jr high wrestling met

5ft6 male here and I weigh around 155/160 (lean and muscular). I'll caveat this with saying I hate cardio, but honestly just get into powerlifting, weight lifting, or Crossfit. I tried a Crossfit gym once and didn't really like the whole "team/group" setting since I enjoy cranking up my headphones and doing my workouts alone. One of the benefits of being short is that you can put on some serious muscle and actually look much bigger compared to the same frame of someone who's like 6ft+ for example. Instead of cutting down weight I'd maintain whatever you're doing and just start packing on muscle, you'll trim down quite a bit anyways with the added workouts. 

Like others have said, if you want just weight loss, I'd vote cardio. For total health? Cross-fit is probably better overall, but remember you'll hit an inflection point since muscle is way more dense than fat and even though you think you're smaller, your weight can start going back up (in a healthy direction mind you). Personally, I'd vote for an all-body exercise like swimming or rowing instead of muscle zone specific exercises, like where after you've been just lifting for a while you look like a Lego man because you can't put your arms down due to bulk but you have chicken legs. Do you want to be shredded like Iko Uwais or Yayan Ruhian or earn a nickname like "The Rock"?
