Even just using the correct language terms is helpful. IntelliJ modules contain packages, because that's how Java works, which makes it super confusing when your modules are python packages and its subunit (called package in the UI) is a python module.
Yeah by the time you need two IDEs you might as well just get the suite.
It also worked out well for me because I bought Ultimate on sale, and the suite was discounted for existing owners. So it's really been good savings. Regardless, given the time savings the IDEs give me, they pay themselves off pretty quickly.
Given the individual license cost difference between IntelliJ Ultimate and the All Products Pack is minimal it’s worth it, especially given it’s cheaper than IntelliJ + CLion separately.
