I do use Chrome's. It does work way better than FF, but you'd be surprised at how much text out there is loaded with third party JS or flash and doesn't "grow" with the the zoom.
You might wanna try Opera 12. It's going the way of the dodo, but it has always had the best zoom of all browsers. In my experience there are only some few video applets that don't zoom properly because they render in exact pixels.
