Hello Sevi
The payment plugin, basically, allow users to enter credit card information directly on your site for processing payment. However, it is only supported in certain country like US, UK, Canada and Australia
Now aday, PayPal recommend to use PayPal Standard Checkout payment method. So I would say you can keep using the original PayPal payment plugin comes with the extension or use MP PayPal Standard Checkout payment plugin. Please note that MP PayPal Standard Checkout, unfortunately, does not support recurring payment yet
