I often have all three of CLion, WebStorm, and PyCharm open. I'm pretty sure I could use IntelliJ for all the use-cases, but the configuration presets make it easier to open all three. As far as memory use goes, I've not had problems -- it seems much more that resources scale with the number of projects open, rather than the number of IDEs open. I open polyglot projects in whichever IDE is the closest superset of the languages it uses. Which normally means whatever language the service is written in, and plugins for other languages.
