I'm definitely on the "breast is best" team, as it's natural and good for mother and baby in many ways. I was devastated when I had DD though as I was determined to breastfeed, only to be told she couldn't suck properly and wasn't getting enough. I then expressed as much as I could and gave it to her in bottles, and she still found it difficult. I had to use fast flow teats just so she got enough, and in the end switched to formula as my supply decreased. I felt so guilty and even tried to bring my supply back up and tried to get her to take to the breast again after she had got the hang of sucking properly - but as it goes, she was used to the bottle by then. :(
Still, i'll be trying again with this one as every baby is different!
I'm lucky too as DD has never been ill, and i'm rather proud of that, and just goes to show you can still have a healthy baby who is FF :)
(I've always been a bit of a health snob with her food though, no jars or anything, I wasn't even keen on rusks because I hadn't made them myself
Still, she now chooses veg over chips any day so I guess my snobbery paid off. Maybe I was making up for the fact I didn't BF)
But women should not be judged for doing either, and FF has it's benefits, like handing the baby over to someone else for feeds while you get some much needed rest, and the Fuller For Longer trick so they sleep better 
Sorry for rambling! Hope everyone is well today :)
