Confusing what this thread is about. Paypal offers web payment standard which is extremely easy to implement utilizing the button. It also offers a web payments pro solution which is a full blown gateway API.
I've used both, I still believe web payments standard integration and more importantly implementing express checkout offers a worthwhile convenience to your customers. A lot of ours use them both.
If we're talking about Web Payments Pro, I've had positive experiences with it for many years and is the primary way I implement credit card processing. This is transparent to the customer as they don't know how the card is processed directly on your site.
The biggest downside to paypal in general is using their administrative portal/ web back end. It is a mess of new and old UI from years past. It is frustratingly slow if you do any quantity of shipping labels from there. Shipping labels at the very least should have a notification api similar to IPN. Bugs are common in the portal from my experiences. Pro accounts also have an additional portal which yet again is a totally different UI experience, very confusing. Overall those are my complaints as a merchant member.
