I've never used Chrome so I don't know if it's better or worse.

My point though is that it's first in recent years that we've had tools like these, and they made a huge difference for me helping me undesrtand what the hell goes on with the styles. It's a much nicer workflow than the old edit-reload-check-edit-reload-check model, where you inserted coloured borders to see exactly how large your divs were, and moved things a few pixels at a time until it looked right.
