Well if you want a real world comparison:

We migrated a project a few years ago from Eclipse to IntelliJ. Outcome:

• Complains about the IDE dropped from around 10 per day to nearly 0
• Onboarding people now takes 1h instead of a day, because IntelliJ knows how to store configuration in a project
• IntelliJ has a built in updater and nearly everything works after an update
• IDE Fuckups: 1 per week (Eclipse) -> 1 per year (IntelliJ)
  • Somehow still happend? Just click “Delete caches and restart” in IntelliJ
• No sources and javadoc for a library available? Eclipse: Have fun reading bytecode; IntelliJ: Yeah I just decompiled it for you within 10s

So yeah I wouldn’t recommend going back into hell. Even VSCode and it’s forks are likely better at this point.

It is NEVER time to go back to the hell that is Eclipse.

Go to frigging notepad or kedit before Eclipse.
