Biggest Search engine in 5 Years

I go with Google. Google is the biggest search engine in this 5 years. Google has launched so many services. And it's very user friendly with all users and newbies.

Said a number of times that I can see Facebook morphing into search engine land, so wouldn't be surprised to see it eventually out strip google.

Not convinced with Bing though, if FB goes this direction, they will drop Bing as the default engine, and as the Bing advertising campaign has ended, I've seen a dip from Bing traffic, and only a small spike while the TV campaign was under way.

Be interesting analysis to see how effective that marketing campaign was for Bing versus the cost.

I personally think, Google is the best

Facebook will crush Google, I expect them to stay in 2nd place though and to fight hard to stop Facebook.
