Yeah, Google is the best for many reasons, like its fast. The home page is simple, and only have a search box etc
Google is the best because it provides the most relevant search results and because the majority of the internet users rely on google.
Google is neat and clean, Results are so fast and display like what actually the searcher wants. No highlighting and Flash advertising are giving to Google.
When you mean google is the best do you mean in search or in other areas as well because if your only talking about search then yes google is the best largely because of its result if you mean in other areas beside youtube google doesn't lead the market place its basically a one trick pony.
I like websites, which you can find very fast what you are looking for. Google is a search engine and they designed it as a search engine. Yahoo is a good search engine too, but you are always confused, what you are looking for by Yahoo.
So easy to use, the services they have are awesome. I've only ever used Google, I don't use Yahoo! or MSN.
