Paypal is probably the oldest and most popular online payment system in the world. It is widely accepted and used due it's reliability and security which comes from many years of operations. Drawing from this, you'd expect me to choose paypal as my preferred means of online payment. But unfortunately, paypal is my least choice when it comes to online payment. This is because am yet to experience the full benefits of having to use to paypal account. Am from a PayPal restricted country, which means I have limited access to paypal services. I can only make payments with PayPal. Hence, it's most likely for me to pick a different payment processor as my preferred mean of online transactions.
Skrill on the other hand is quiet new compared to paypal. But from my personal experience, I think skrill is a strong contender when it comes to online payments. Their services are fast, reliable and easy to use. Almost every country is allowed on skrill with full benefits of their services which are way less expensive than that of paypal. I've used skrill a couple of times and I haven't any cause to complain. Hence, i'll like to state that skrill is my preferred choice of payment over PayPal.
