Which search engine do you prefer?

I use prizewish because you get what is called swag bucks. They add up pretty fast and then you can cash out for gift certificates. I just cashed out for a subway gift certificate and it came within 5 days. I was shocked. Most times when you request something it takes 6 - 8 weeks to get it. You can also buy things through prize wish and get credit but I haven't done that yet.
