It does matter to the user. A Java based tool requires installation of a JVM and likely has a non-trivial startup time. A Python / Ruby tool requires a runtime and probably some kind of mucking with virtualenv or rvm to work properly. A Node.js tool would require (haha!) a Node runtime and crossing your fingers that the NPM dependencies for what you're going to use to connect to your database haven't been compromised since the last build. A Go based tool would be statically compiled, start up quick, and not have any external dependencies.
