In my opinion SEO is better due to the simple fact that it's free, and if done correctly, can be far more effective than PPC engines. If your site is SEO good enough, you will be taking sales from the other sites that are paying for the PPC engines. I've seen it happen before. It's all about dedicating a lot of your time promoting your site. Link backs from well known, established sites with a high page rank are essential for a top position in Google also.
