Well, fryke, that's true for some people (maybe even most people), but not everyone. The Discburner framework (which those three use to burn CDs) doesn't have support for near as many burners as Toast does.
Like me, for instance, my burner isn't supported. I've found a little hack that makes it supported, but it doesn't burn at its full speed as a result of that. Until it is supported, I'll most likely be using Toast more than the Finder or iTunes or Disk Utility to burn CDs.
