Which would you recommend; Braces or Invisalign for a severe case?

I'm a 15 year old boy going into my sophomore year of high school. My teeth are very crowded and my bite is off. My ortho gave me Invisalign and the first two days were awful. They put 16 attachments ok my teeth, with rubber bands and the trays. It's terrible, my mouth hurts so badly, my gum is swollen, and it takes me 45 minutes just to get the trays in. I've had second guesses ahour starting Invisalign and I've had thoughts about switching to traditional braces, would you recommend this?
