How do I use the Google search bar?

Do you use the google search bar in android home page, what do you use it for? Do you use it more often than Chrome?

It seems useless to me. If I tap it a new page pops up with a search bar to let me search for something, it does not appear like a real chrome browser, no new tabs function, no history. A chrome browser works better.

Not sure what is good about the google search bar and why does it need to occupy 4 icons length, I intend to remove it and make space for 4 icons.
