Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

JetBrains IntelliJ IDEA

  • High memory consumption and slower startup time compared to lightweight editors like Visual Studio Code
  • Refactoring can sometimes increase code line count and doesn't effectively support all modern programming languages
  • Occasionally misses dependencies between files requiring full rebuilds for consistency
  • Expensive subscription costs for Ultimate edition compared to open-source alternatives like Eclipse
  • Not all class name references are updated reliably when using search and replace functionality

RubyMine

  • No permanently free tier for commercial use; requires an ongoing subscription.
  • More resource-intensive than lightweight editors such as Sublime Text.
  • Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead.
  • Startup time can be slower than simpler text editors on older hardware.
