I like C more than Rust because for my taste, Rust is too complex. I also like that C has fast built times which is important to me. C is also far more portable and has a huge ecosystem. Another big win is that you can gradually transition older code base, while I feel the "rewrite in Rust" approach throws out the baby with the bathwater. Generally, "rewrite everyhing" is often infeasible and even if it is, it is usually misguided. Another thing is that to justify rewrites, one has to over exaggerate the benefits of Rust via the problems of modern C (I don't doubt there is a lot of rotten old C code around), which poisons the discussion.
