Almost everyone will have different results per program to a degree just because of the wide amount of variables that can factor into the overall equation imho.
Sticking with well known programs to start with is good advice. That allows you to learn things without the fear of being scammed like some unknown places are more apt to do. The biggest thing with any sponsor dealings is not to assume anything! If you want to avoid hassles, build up good relationships and so forth, ask the sponsor your questions before proceeding if you are not clear on anything. A large amount of issues that could arise may be avoided all together this way.
(With all that said, I'll now mention that I've been promoting CE Cash since well before I was working with them and I've always been very happy with the results
