To be honest with you, there's really no other payment processor that can be labeled as better than Paypal. This is because most people prefer using paypal. So even if you find a very good payment processor like skrill for instance, you might still be faced with problems in the process of transacting with others since most people prefer using paypal.
The unfortunate problem with paypal is that it doesn't extend it's full services to all countries. Paypal has placed restrictions in many countries. Some countries are not allowed on paypal, while others are allowed to operate only a transfer account with inability to receive funds. This is probably the reason why online operators seek an alternative to PayPal. Am guessing you're probably from one of those paypal restricted countries. If so, then they are quiet a few other processors who can almost meet up as substitute for PayPal.
Skrill is one good payment processor which is gradually becoming more accepted and used online. Although it is yet to be accepted by all, it still can be of great services like paypal. It's services are fast, reliable and of low charges for transactions. However, there's still the problem of transaction fully with it like said above. Some merchants do not use skrill, hence, you'll need some type of exchange services to be able to transact with paypal users.
