Difference between WPMU's Affiliate plugin and Tips and Tricks Affiliate plugin?

Can you tell me if your affiliate plugin is better or the same as another one that I found at http://www.tipsandtricks-hq.com/wordpress-affiliate-platform-plugin-simple-affiliate-program-for-wordpress-blogsite-1474?

I was curious if you could tell me the differences between the Affiliate plugin from WPMU and this other one?

Thanks,

Gary
