The first one most people run into: Nim is roughly as performant as Rust, but it's easier to learn because it's garbage collected. But it's also not garbage collected, if you prefer (with caveats). Want a different flavor of garbage collected? We have three (with caveats)!
thats not a different way of doing same thing, its doing different thing. this not even an argument, if language can provide multiple memory management strategies, in what world is that a bad thing?
and if you somehow confused about choice (of gc), you should stick to default.
also, there is no such thing as "There is Only One Way to Do It" languages. your entire argument is just a circlejerk point.
Is Nim garbage collected? There is no simple answer to that.
When it is garbage collected, how is it garbage collected? There is no simple answer to that.
As stated in my original comment, I prefer languages which are more opinionated than that. Nim is a Swiss Army knife; some people like that, but I prefer choosing a fixed-blade knife to suit my current purpose.
Is C garbage collected? There is no simple answer to that. Link with Boehm (or something similar) and it is. These things are often (with almost any language) aspects of the implementation & deployment, and most mature languages have multiple answers as well. Is Python "compiled"? Well, with Pypy or Cython or etc. it is. (Or maybe it's always at least "compiled" to byte codes run by a slow byte code interpreter.) Etc., etc. I think your standards for "simplicity" or univalence may be, as @SolitudeSF alluded to, unsatisfied by even prog.lang's you like (which you gave no concrete examples of).
