Is recurring basically if I want to sell a product, instead of a subscription? I read that it allows people to buy a product and just continue to log in to DL it... exactly how it is on this website here. That is true, correct? Basically, I sell a product and want people to have access for the life of the site... so i guess 10+ years.
I don't see big difference between a product and subscription Anyway, if you have ONLY not-recurring products, use "paypal" plugin, if you are asking about.
