I used to have licenses for IntelliJ, RubyMine, and PyCharm. The customized IDEs are nicer to use: feels more light weight.

Now, I just use IntelliJ for the occasional Clojure and Java. If I need RubyMine or PyCharm, I just use the old versions I am licensed for.

If I was actively using Python and Ruby then I would keep the licenses up to date - well worth it.
