Considering nexplanon(?) implant - stories?

I take the pill currently but am not as consistent as I’d like to be. I’m considering the arm implant which lasts 3 years. Can anybody share about their experience with the implant procedure? And periods after its in place? Any pros/cons about getting this instead of an IUD? I’ve heard IUDs are painful so I’d prefer the implant - but am I missing something? Gonna read the pamphlets my doc gave me too. Just curious about others’ experiences.

Thanks in advance!
