Google engine has always been the best engine in this earth and will be.
Google search engine is the fastest and I have also tested thet in 0.45 seconds it loaded over a 16000 sites in front of me.
It also works with a slow net speed and the best thing is that it will give you the accurate result according to your search keywords.
I always uses google for my search.
I will recomend you to use it only.
Its also ads free.
