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.
