RAP Beats ClickBank
At least some of the time. 
I've toned this down a bit lately.
The Rapid Action Profits program is gaining momentum rapidly. It has so many advantages over CB that it is the focus of my efforts now.
CB certainly does have advantages too. They are much better known and might have a thousand times more products. I am there often enough looking for something good to promote and just bought one yesterday, Paul Walker's Affiliate Cash Ultimatum. It is impressive.
It's just that I go to RAP first looking for products because of the simple pay arrangement.
There are a lot of requirements before you can collect your first pay with CB. You can skip them all with RAP systems.
My first experience with a RAP product was the one on the Website Flopping page. The page includes a few details about the first money coming in with it. It was just a simple PayPal email saying that money had been added to my account. You don't even have to check your affiliate accounts to see if you have sales.
Just the waiting time until pay day can be a pain in the neck with most affiliate systems, not just ClickBank. In addition CB has requirements like 5 different credit cards must be used before you get your first check. There are also other requirements, like purchases must be from different areas etc. I have seen post after post in forums with people complaining about these first pay day requirements.
It's fine if you have a huge site with massive traffic. It might take a very short time to meet them. If you are just starting out things might be different. They certainly were for me. Happily that has turned around and RAP products were the first to start making money for me.
Another little problem with CB is that if you don't make a sale for awhile, the account is charged $1 periodically for inactivity. (sigh) Combine this with most products taking a lot of traffic to make a sale and you have a recipe to drain a small account.
I'm not even saying this is bad. A lot of businesses including most banks will charge you to keep an account open. It's just a hit to start out finances, and to wimpy little sites like most of mine.
With RAP there is just no possibility of charges like that. That kind of bureaucracy takes a hit in the head and doesn't get a chance to mess with your money.
The Tedious Details
I should mention a couple negatives that I know about. Some of the products pay 100% commission. The vendor uses this to get a lot of them out and to expose his affiliate links in the ebook. Or he might make money from up sells once the first product introduces him and his program.
A small disadvantage happens to the affiliate when the commission is less than 100%. As an example, when the commission is 50%, the first affiliate sale will be credited to the vendor's account. The next one will be to the affiliate's PayPal. It will alternate like this to keep the split at approximately 50%. However if the affiliate never sells another, their commission will be 0%. They will never get the sale that goes into their account.
Another more significant disadvantage right now is that they don't have nearly as many products to promote as CB. Their products are growing rapidly though, and for the first time I wouldn't be surprised to see a company overtake CB. In fact, I wouldn't be surprised if CB gets clobbered.
