Well I respectfully don't think this is a good analogy. In the case of tools, each tool does something different with little overlapping functionality.
Frameworks on the other hand all do the same end task which is build a site, but have different footprints, modules, support for xyz libraries i dunno (I myself am new to frameworks)
So it would be helpful if there was a comparison matrix out there somewhere. Wikipedia has a comparison matrix of web development frameworks across all languages, but it's kind of metric based and non-descriptive, un-meaningful in english
