DS was a fairly traumatic hosp birth - home birth had been planned until my bp went up slightly towards the end of my pregnancy. Waters broke normally at home, contractions a couple of hours later, got into hosp 5cm dilated, but he was back-to-back, they couldn't get a trace, so insisted on me being stuck on the bed to montior DS through my vagina (sorry, don't know the technical way to put that!) which of course delayed things and didn't give him much chance of turning either. Consultant insisted on epidural at 9.5cm, which then delayed things by another 4 hours, had to have a drip to kick start things and consultant wanted to do c-s but I pleaded so they tried ventouse, 3mins later he was out. I was fairly traumatised by it all after (of course, first baby I imagined I was going to breathe through the pain, need no drugs and it would all be relaxed and pleasant)!
2nd time around, my midwife booked me in for home delivery, I wasn't actually sure if I wanted that this time (felt exactly like you) but thought it wouldn't harm to go with it, then I could always change my mind and go in if I felt I needed it. 40+2 midwife told me the baby was OP again, but she was happy to still deliver at home. 2 days later contractions started, was 5cm when midwife arrived, progressed much quicker at home, was much more relaxed and felt more in control - was also prepared for the OP position meaning I'd feel the urge to push much sooner than I could actually push and understood what my body was doing, G&A was also my NBF! however, when my waters went, there was meconium in them, so I had to be transferred in at the last minute! DD arrived 30m after getting into hospital, it was really relaxed in the room, they had a couple of doctors on standby to check the baby over due to the mec, but they didn't interfere or even speak to me - the midwife just got me on the bed to check heartrate etc. when I said I needed to push she said go for it and really it was just me and DH that were invovled in the hospital bit. They whisked DD away to check after we'd both had cuddles, 2 mins later she was back with me feeding happily.
So in a way I had both home and hosp 2nd time around, and both worked really well. I think you'll be more prepared for it, you'll know more about what can happen and I'm sure it'll be much more positive, whatever you choose - good luck! - oh, ask your midwife to get hold of your hosp notes for the birth and go through them with you as a de-brief - that helped me greatly before the 2nd birth.
