Where each one falls short

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

LaunchDarkly

Pricing scales rapidly with monthly active users, becoming expensive at scale
Limited seats for engineers on standard plans, forcing upgrade to enterprise
Advanced features like experimentation and audit logs require higher-tier plans
Occasional reliability issues and backend delays reported by users

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.
