I love Rust, but I love and recommend ripgrep because of its usefulness, reliability and robustness, not because of the language it's written in.

I haven't looked into all the tools in that list, but I would not for example recommend exa over ls as it is simply not reliable enough: if a filename ends in a space, you won't see that in exa, and that bug has been reported for years. To me that is a clear blocker, and if it is still there, I simply cannot trust the file listing from exa, no matter how pretty it may look.
