Browser zoom vs text zoom. Which is better?

Question

I noticed that you guys have a text re-sizer on your site. Why not just allow the user to use the browser zoom? Is one better than the other?

Answer

The criteria stated in 1.4.4 says that the text must be resized without the use of assistive technology. This means that there needs to be a button on the screen somewhere that allows users to click on it or tab to it.
