Get the project 'A' features and compare with project 'B' features, the strength and weakness of programming languages will be apparent, on the features, runtime speed, bugs, etc..

Choosing a project over another just because its in a given language is not based on logical reasoning, but emotional reasoning and therefore the bad paths will get evident with time (Except of course if the language is really unsuitable to the domain, which is not the case here whether with C or Rust).

This emotional bias for me is a reason to actually look at Rust projects with suspicious if people working on it know its just another tool with some given properties and not some magical wand that will turn everything into unicorns and rainbows.

Note: this is also targeted at "why you would want to choose C over others ?" comment bellow in the same line
