I worked significantly in both Django and Rails, and I found the most magical part of rails is its ORM (ActiveRecord). I find both SQLAlchemy and DjangoORM both more awkward and less natural to use, both for the query side and the relationship definition side.

Once the data is loaded into memory, everything else is just syntax.

At this point, I only reach for python as a web application if I need to build something that has AI / ML features. Rails apps I've built in the past that needed to call a local model resulted in having to create a python inference microservice, which kinda sucks.
