What Kind of Paypal Account do I need for the Membership Plugin?

What Kind of Paypal Account do I need for the Membership Plugin? I have a site where people will pay for different membership levels (monthly, quarterly, yearly) and so there will have to be some type of reoccurring payment functionality in the Membership plugin that works well with Paypal.

I went to sign up for the business Paypal account and there are two options: 1) Paypal Payments Standard and 2) Paypal Payments Pro. Which one of these account types do I need?
