> Majority of learning surface will come from framework and not the language

Once you get past the beginner level in Django, you're going to pick up a ton of Python knowledge (standard dunder methods, MRO, standard lib, data type's im/mutability, package ecosystem, etc.) and muscle memory along the way. Django (for the most part) is just plain old Python data structures, classes, and functions that a decent Django dev will apart, reuse, override, repurpose, and add on to as they do more interesting things. Python is boring (in a good way), however it has a lot of surface area (std lib is massive) and intricacies that a Django dev will pick up along the way to becoming an intermediate/advanced dev. It would take someone coming in fresh to Python quite a while to catch up. Naturally, if the same person knew several languages, the ramp up would be quite a bit quicker.

Ruby, and Rails in particular, has a lackluster dev experience with any editor that isn't RubyMine. That's been a huge obstacle for me personally.

Each to their own I guess.

Personally I like the ruby-lsp and TPope’s Rails plugin in NeoVim.

I dislike heavy weight IDEs, I never find the juice is worth the squeeze.

I want to like ruby lsp but it takes about 8 seconds to get method references in a large monorepo. It’s simply not good enough, and forces anyone looking for a good devex into rubymine

I'd suggest maybe trying either Solargraph[1] (which also works well for me) or a ctags based solution like ripper tags[2].

On the plus side, ruby-lsp is always being improved and worked on, so just like Ruby in general it's only getting better at what it does.

Although a bit annoying to install I am still using the rails plugin for NetBeans.

I just never switched to Aptana or Rubymine and now I don't wanna.

ruby-lsp and rails-lsp from shopify is pretty good right now and getting better by the day. the vscode extension handles it well too.
