So which got more efficiency here,google knew what you want but while browsing anonymous browsers we may have to spend more time for finding the same,I am not encourage their spying behaviour on every user but at least it won't be a problem for most people.
Spending more time to find the same - a little misunderstanding we got here. I don't want to google give me the results i know he will give, because of my search history. Sometimes anonymous browser gives broader search and that's what i'm looking for, to know the topic i search for better.
