I'm happy with IntelliJ (>9 years of ~daily use), but if there are long-term users of Eclipse here who are familiar with both and prefer it to IntelliJ, I'd be interested to hear why.
- Eclipse type hierarchy view (and quick view) was nice
- Google-Java-Format plugin integration was better
- The default color scheme of Eclipse was better (not sure why but I can't use a dark theme with Java)
But Eclipse had too much strange behaviors where I had to restart it and IntelliJ has those warnings/suggestion about code quality and better auto-completion IMO.
I moved to intellij because the simple things I needed just worked out of the box, and I mostly find it great.
But I'd still like to hear from someone with a different take on it .
