Breastfeeding Vs Formula Feeding?

My fiancé wants me to breastfeed our little girl since it's natural and more healthy, and he was also breastfed. But i'm not sure if I want to because i'm a working lady!! I only have 16 weeks on maternity leave and i'm not sure how I will feed her when I go back to work? And it seems so much more harder in terms of feeding in public or on the go. What is your opinion/experiences on any of these nursing tactics?
