Like everyone else here is saying I recommend RCT. I got my 2nd lobes done at Lucky and they managed to pierce one of them crooked so I had to take it out. If they can't get a lobe piercing right I wouldn't trust them to do a cartilage.

That being said I have friends with a ton of piercings, all of them from lucky and all of them fine so depends on your risk tolerance/how frugal you are.
