The last one I tried was ripgrep, and something about the default behavior just drove me insane... I'll freely admit that it's all about aesthetics and there's no right answer, but that doesn't mean my preferences go away ;)

I'm glad people are enjoying rust, and sure, memory safety is nice. Fun and comfort are even better, though, so I'll stick to C, Lua and Go for my personal projects.
It's like when bands cover songs. Who cares if another band plays the song if they don't put their own spin on it?
So it's more that you don't care for the tool than the language in this case. Although, I invite you to try ripgrep again and/or lay out some of your gripes with it. I find it a very good replacement for grep.
