I prefer a crib. my daughter reached the 15lbs weight limit for the bassinet attachments on pack n plays at 5 weeks old. without the bassinet attachment it's so hard to transfer her to the pack n play so low to the ground. but our crib we can raise the mattress and it makes things so easy. your babies crib (or pack n play if you have one) is the safest place in your entire our for your baby. so if you don't trust things like blankets, stuffed animals and bumper pads, then just don't buy them for the crib.
also in my experience. every pack n play I used regularly for my oldest kid got worn out and very uncomfortable for her, and eventually she was to big to be comfortable in one. plus even more so, a crib eventually converts to a toddler bed with is extremely useful.
