Playpen or baby cot?

I'm 7 months pregnant and have been researching and looking to buy a playpen or baby cot for my baby, but I'm not sure which one to choose from. We are interested in getting this JOIE playpen which comes with a diaper change station and a rocker/bouncer. The playpen can be converted into a bed or later a playpen when the baby grows up. Can anyone advise? Thank you!
