They all do different things.  The only one I don't use is Yslow, just never tried it.

Fiddler sets up a proxy in your browser to capture what your browser is sending and receiving over the network.  I don't know of a similar tool to Fiddler.  Wireshark, for example, monitors all network traffic, not just what involves your browser.

Firebug is a troubleshooting tool for Firefox.  There are similar features built into Chrome.  It allows you to examine and change HTML and CSS.  And I believe PageSpeed is available as an addon for it in Firefox.  The Net tab shows some of the same statistics as PageSpeed does.  I have an addon that also analyzes CSS on a page and shows you what is and isn't being used.

Google's PageSpeed analyzes web site performance.  It makes recommendations to 'improve' the performance of a page although if you are careless about implementing their recommendations, you can actually make things a lot worse instead of better.  I don't know if Google takes their own advice... but then they have millions of server machines to implement whatever they want.
