I have done both (bottle and breastfed) and for my money bf is easier (long term, can be tough to initiate and settle in no question), cheaper, an so much more versatile. It is so much more than a feeding method, it's a parenting tool. Baby hurts themselves? Breastfeed and it floods them with both pain relieving and comforting hormones. Teething? Instant pain relief and comfort. Baby sick and refusing solids, only wants to cuddle? Bf. Baby vomiting and struggling to hold down fluids? Bf is easy on their tummy and if they do chuck it back up, doesn't stink nearly so badly as formula puke (plus you haven't just 'wasted' a load of time and money on making up a bottle). Baby refusing to sleep at bedtime? Bf until they zonk out 😆 Gone out and forgot to pack snacks/cup, or get stuck out longer than you planned for? Food and drink on tap. Baby bored and being a pest while you try to talk to a friend? Whack em on the boob!
ALL THAT BEING SAID: my first baby had an awful latch and CMPA an ripped my nipples to shreds. It was no joke and it did not "come naturally" - took us about 6 very VERY painful weeks to find our groove. Also because of her bad latch she wasn't getting much on board so woke up every 20 minutes in the early weeks which nearly killed me dead before I learned to feed lying down. La Leche League and an online support forum helped so much. If I hadn't been so (possibly unhealthily) fixated on breastfeeding due to unwanted c section related birth trauma I could easily have given up at that point.
My second baby I was much more prepared - but then she just wouldn't feed AT ALL, flat out wouldn't latch on. Screamed when I tried. Was squeezing out colostrum into a little syringe and squeezing it onto her tongue. It was awful. Midwife visited and saw what a state I was in, saw that the baby was giving signs of low blood sugar and recommended formula to tide her over and she guzzled it down from a newborn bottle - it was such a relief to have her fed. Made me realise what an amazing invention it is, possibly for the first time. I then got a pump and from the next day she was on exclusively pumped bottles (I was lucky that I had little trouble with supply). I found pumping and bottle washing etc a total admin ballache though and hated it, so persisted with bf (mostly at night when she was sleepy enough to be relaxed about giving it a go). By 6 months we were "mixed" breast and bottle, by 10 months she sacked off the bottles herself and was exclusively breastfed. Still going now at 19 months.
I would say the convenience of bottle feeding (if there is any) is in the bottle, rather than the formula, and if I wanted to bottle-feed for whatever reason I would pump for it. Once I discovered in-bra hands free pumping it changed my life, before that pumping was such a nuisance, afterwards it was just so so easy.
I guess my point is it depends what you want out of it. For me, bf solves a bunch of problems an doesn't cause any past the initial weeks or establishing. Bottle feeding caused a lot of issues. But for me, I didnt have to or want to be away from my babies when they were small - if I had needed to, pumped bottles of breast milk would have been my solution.
