Which is best Google tool in point of view....?And why?

For seo web master tool is the best tool in google.

Ajax
 

For me, it's the ajax. Using the Google Ajax Libraries API is advantageous for many reasons, including the reduction of web server bandwidth and resource consumption and a higher chance that your site visitors will hit your web pages with a primed cache because they might have visited another site that uses Google Ajax Libraries previously, producing faster page response times and enhancing their experience.

Google webmaster tool is the best Google tool according to my opinion. Because it provides all the guidelines for SEO (Search engine optimization).

I think Google webmaster tool is best.

Google Adwords is the best google tools.

Google Webmaster is the best google tool, It is the primary and most important tool for a website. Because Google Analytic tools also depends on it to provide search queries but there are still limitation you can know about referral traffic without help of Google Analytic tool.
