Where each one falls short

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

Helix

  • No official GUI application yet, so it requires comfort with terminal workflows.
  • Plugin ecosystem is far smaller than Vim's or Neovim's, limiting customization.
  • Keybindings differ from both Vim and Kakoune, adding a learning curve for users of either.
  • Configuration is more limited than Neovim's Lua-based extensibility.

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
