Sell me on your video sales/product sales sponsor program

Hell... sell all of us on it. I've tried out various video sales affiliate sponsors and been less than thrilled about all of them.
Now, not trashing them in the least. Some definitely have some pretty cool features, some are good enough, have earned commissions with them all.
But it definitely seems that membership site sponsor programs, on the whole, are way more developed, advanced, and comprehensive than video sales/product sales affiliates. And I'm not just talking about the percentages involved - I mean the features they offer, the promo material they offer, live and comprehensive stats (this one most of all), cust. service, so on so forth.

So... if you have a video/product sales sponsor program that you think people should try out... what makes it so great?

And if you're like me and still on the hunt for that wonderful video sales program... what do you want to see in them?
