Compiler output only marginally better than working with c++

No one claims it's faster at runtime than good C++, it's just a lot easier to write decent code

I think they're referring to warning and error content. Compared to things like rust, deciphering error notifications from the c# compiler can sometimes feel like trying to figure out what a child with limited vocabulary is trying to tell you.

Even with decades of personal experience with it, they can be confusing and non-informative sometimes for me.
