PyCharm is cheaper than Ultimate, and more focused on Python dev. It's far easier, in my experience to set up PyCharm or GoLand for a Python or Go project than Ultimate.

And yep, can run ancillary plugins to an extent, I don't think you can run, say, the Go plugin in PyCharm, for example, but JS/TS is out of the box IIRC.

Another thing I've noticed is that the IDEA Ultimate plugins tend to lag the features introduced in language specific IDEs for a bit.

JetBrains offer a multi-IDE licence that costs slightly more than Ultimate, worth looking into for polyglot development. But I went for Ultimate for our Python codebase because we're using a lot of FOSS JVM products, and super easy navigation around large JVM codebases to read code to understand some observed behaviour is very much worth it.
