Ah, ok. Valid points, and I can't address all of them, but I kind of have experience of all 3, so I'll tell you about it in case it's any help...
I went into labour naturally at 40+8. My contractions started off just 6 minutes apart, but that was still the case 48 hours later! I was exhausted (contractions were too strong to sleep through) and tearful and ended up begging labour line to admit me to the ante-natal ward for some pain relief. As I was only 3 cm dialated, all they would give me was pethidine (took the edge off, but not massively effective).
Whilst on the ante-natal ward, my contractions finally became more frequent and I got to 4 cm dialated, so they let me have an epidural. However, I remained at 4 cm dialated for the next 12 hours! During that time, they pumped me full of induction drugs to get things progressing and it was completely ineffective. But having had the epidural, I wasn't the least bit uncomfortable. I caught up on sleep, I read magazines - it was far better than the latent stage of labour!
In the end, they decided that DD wasn't going to come on her own and so did an emergency c-section. I've had a lot of surgeries in my life an the c-section was one of the more major ones, yet it was surprisingly one of the easiest to recover from. I didn't have much pain, was moving normally within a couple of days and comfortably walking into town (a reasonable distance) and back after a couple more. I'm now 33 weeks into my second pregnancy and have opted for an elective c-section this time.
So I suppose what I'm saying is that from my own experience...
C-section: not necessarily a longer recovery rate
Natural: not necessarily less lengthy
39 week induction: not necessarily more painful
