IUDs vs Nuvaring vs pill?

Raleigh
I'm getting back on birth control next month and I want opinions on side effects/symptoms for different kinds of IUDs (copper vs regular) and Nuvaring and if you think they're better than the pill. I don't care so much about weight gain or acne because I can take care of those issues but mostly pain, mood swings, and spotting/bleeding. Any advice?
