Payper view plugin and memberships plugin

Hello,
Im checking Pay per view and Memberships plugins right now, and im not sure which one is "correct" to use it in an online Magazine website. Model of payment for that website is to offer few free articles per month, and for premium users to offer more speciallised content. And once in a while to create a usefull PDF and sell it.
What is your suggestion for this scenario? Which plugin to use for?Or both? Are these two plugins cooperating together?
Thank you for your time,
Best regards,
