As a full-time Ruby developer I absolutely loathe code which drops the parentheses from method definitions that have arguments.
Have you tried Rubocop? It automatically reformats code according to an opinionated style guide (which I think aligns with your opinion).
When I first came across Ruby -- and particular Rails -- I loathed it. Ruby's syntax allows you to get pretty creative, and jumping into Rails + Rspec is like jumping into a Perl repo that's been managed by 3 different people over ten years. There's all kind of things that -- because the syntax is so loose -- it's not clear what's going on. It doesn't help (in my opinion) that Ruby's own style guide almost encourages this: dropping the "()" from functions that take no arguments; Eiminating "{}" around certain hashes passed into functions; The "!" marker having a seemingly different meaning in almost every library, etc...
When you're new to Rails and Rspec, it's easy to have no idea what's going on.
That being said, you can prototype an entire business in a few days Rails. It is that easy. It's incredibly polished. It's opinionated in mostly right ways, and all of its libraries are, too -- which means you don't often find people doing crazy shit (except Devise, everyone is always doing something crazy with Devise).
As much as I hated Rspec with a passion, I do feel like it's the best testing frameworks I've ever come across. It lets you be SUPER expressive about what you're testing.
I go against the Ruby & Rspec style guides on a few things, but I feel like no other combination let's you write code that's so expressive.
And, finally, anything you want to do in Rails has a library built in that does it very well. And unlike in -- say JavaScript for example -- there aren't ten libraries to pick from. There is a clear winner, and I think that's good for the community.
Also, almost every major API you can imagine has a Rails Gem so that it plays nicely with the framework.
Don't get me wrong, I loved Django and I still think it's a great framework. My love for Python, Elixir, and Kotlin are strong.
Ruby & Rails are by no means perfect, but I do feel like it's a very clear winner if you're starting a new web business. The number of companies I've seen flounder because they wanted an App + a website + (obviously) backend business logic... and all of that in one language, in one code base -- it's impressive. I've seen a lot of Rails businesses fail. But despite what people warn about scaling, I've never seen a Rails-based company fail because of Rails. Plenty have flourished -- Shoppify, GitHub, AirBNB, etc...
I could go on and on about the advantages WRT hiring, too. Don't even get me started...
