Here's our take.

MRI

Nice Pick

Developers should learn and use MRI when working with Ruby, as it is the official and most stable interpreter, ensuring compatibility with the Ruby language specification

Pros

• It is essential for building Ruby on Rails applications, developing scripts, or maintaining legacy Ruby codebases, particularly in production environments where reliability is critical
• Related to: ruby, ruby-on-rails

Cons

• Specific tradeoffs depend on your use case

JRuby

Developers should learn JRuby when they need to leverage Ruby's productivity and expressiveness in Java-based projects, such as enterprise applications, web services, or systems requiring Java libraries

Pros

• It is particularly useful for integrating Ruby scripts into existing Java codebases, accessing Java APIs directly, or deploying Ruby applications on JVM servers like Tomcat or JBoss
• Related to: ruby, java

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. MRI is a tool while JRuby is a language. We picked MRI based on overall popularity, but your choice depends on what you're building.

The Bottom Line

MRI wins

Based on overall popularity. MRI is more widely used, but JRuby excels in its own space.
