Crib or pack n play?

When baby is born are you putting baby to sleep in a crib or pack n play? I'm having trouble deciding between the two. On one hand, I'd like to just have a crib from the start so there's no transitioning baby from pack n play to a crib and also to save money instead of purchasing two different things. On the other hand, my fiance and baby's father is saying cribs aren't safe because of the railings (even though I plan on buying a bumper for that). I'm still leaning more towards a crib but I thought I'd ask for other people's opinions.
