I will admit that the .NET ecosystem has gotten way better since being more friendly towards Linux users/environments and I used to code a lot of C#.

I love both Ruby and C# - I don't think one is better than the other. Ruby also has good interop with C. The performance of Ruby is good enough for most use cases. Scaling a Ruby app via multi-process scaling has worked perfectly fine without major issues for most use cases. The open-source 3rd party libraries in the Rails world have a certain "feel" to them.. as if they were written by devs that care a LOT about the - excuse the trendy term- DevEx that are often missing in the C# world.

Call it bias due to familiarity but Rails continues to remain the most productive option to bootstrap a web app/startup for me. Often I think most of the dissonance is simply due to difference in philosophy. Devs don't like Rails because its not "their way" and not that it is inherently better.

Pick the tools you like to use, most productive with, and most appropriate for the application - thats it. No need to nitpick on language semantics, tooling, or performance if those are not even major considerations for what you are building.
