I have breastfed both my DC. DD until 13 months. Still feeding DS who's 9 months.
May be cross posting as haven't read full thread but here are my thoughts.
Good things:
It's so convenient to do when you're out and about. No kit to take with you or clean. And cheap too! I honestly would not know where to start with prepping bottles to take out with me.
Great bonding, I'm sure you get it with ff too but there is just something immeasurably precious about feeding your baby from your body and looking at their little faces and their hands exploring and gently (and not so gently) tugging and patting you! Not so much the nipple twiddling though...
Good for the figure. With both DC I lost a lot of weight in the first 6 months. I definitely attribute a lot of that to breastfeeding.
Good start to life for baby - controversial I know, and obvs fed is best. And I see no difference in babies who are ff and those who are bf. Except my DC are rarely ill, maybe just a coincidence but hey, it does help to know I'm giving them the best start I can because I've been lucky enough to be able to. Although I do think there really isn't much in it...
Bad things:
The sleep deprivation. I know one or two mums with ff babies who don't sleep but basically it seems if you have a bf baby, buckle in for not much sleep. My DS took formula and bf in his first week (he was premature and wouldn't latch) and he did some great stretches of sleep after formula! Mind, both my DC are crap sleepers so maybe it makes no difference.
The pain in those first few weeks. Have heard people saying it's worse than childbirth, it certainly is agony as baby latches on to your poor cracked nipples at 3am and you cry because it's fucking agony and you are so exhausted. But...it's for a relatively short time and it does pass. You'll suddenly be feeding and realise there's no pain and you're actually enjoying it! PS nipple shields come in different sizes, I had no idea, ordered some at 3am and they were large, only realised my error when they arrived and were mahoosive.
Baby refusing a bottle. I had no idea this was a thing until I had DD. Then DS started to refuse a bottle too. Obvs if they are not taking a bottle you can forget about much time to yourself at least in those first 6 months! It's a bit crap but it is what it is.
Limited wardrobe. Limited social opportunities at night as only you can settle baby. Learning to feed in public. The biting. Not much wine!
But all in all...i love it and I'm going to be so sad when I stop feeding DS as he is my final baby. I'm so pleased I was able to do it, I know that it's not for everyone though and you must do what is right for you and your baby. But it is so worth a bit of perseverance IME.
Good luck
