You can't make baseless accusations of shillage here. We detached this flagged subthread from https://news.ycombinator.com/item?id=12975014.

I can't speak for Linux/Windows but on OSX IntelliJ destroys Eclipse in every single aspect.

And frankly I don't care whether it has native UI widgets or not I just want it to be fast and smooth.

Windows too. I think eclipse is so fubar that many users cant envision that an ide might be dramatically more stable than eclipse.

Whoa there. I was asking a question, somewhat incredulously. Maybe the person who wrote that comment is misinformed. Maybe they know something we don't.

Nowhere did I suggest they were 'JetBrains shills' and neither should you, unless you have some evidence of it.

In the UI options there's an option for GTK but I've just checked (both IDEA and PyCharm) and I think it's just a theme. I genuinely thought it was using GTK widgets.

That is most likely the GTK look and feel that ships with java swing. It is an emulation, not native.
