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

ESLint

Slow performance on large codebases compared to newer tools like Oxlint and Biome
Complexity in configuration from scratch, particularly for TypeScript support
Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

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.
