| Learning curve | Gentle for anyone who knows Python. Batteries-included conventions mean you rarely wonder how to structure things. | Gentle at first thanks to convention over configuration; the same magic that speeds you up can confuse debugging later. |
| Performance | Fine for the vast majority of web workloads; Python is slower per core than the JVM or Node, so you scale horizontally, and async support is still uneven across the stack. | Adequate for most products; slower per core than the JVM or .NET, though YJIT keeps improving Ruby's speed each release. |
The two great convention-driven monoliths remain remarkably close. Rails still edges Django on pure scaffolding speed and full-stack elegance with Hotwire; Django edges Rails on language momentum, AI-stack proximity and hiring. New products with data or AI ambitions lean Django; teams that love Rails conventions still ship faster in Rails.
