rust coreutils aren’t bad, but they are new. They probably work a bit faster than the originals, and they probably are long term more stable… but they are also probably short term less reliable because they don’t have decades of problem solving supporting them yet.
Most people likely won’t even notice a change has happened.
They probably work a bit faster than the originals
There are some commands doing string processing that have been rewritten to use SIMD instructions which makes them inherently faster. On the other hand there are other commands where they’re performing worse than GNU coreutils: https://www.phoronix.com/news/Ubuntu-Rust-Coreutils-Perf
Over time they will probably close the performance gap for those outliers, but if the GNU coreutils maintainers wanted to accelerate the same commands with SIMD instructions they could also do that. There’s no real reason why long-term one should be faster than the other, except for whichever project gets more attention from maintainers.

You get your well measured response out of here.

Oh shit, sorry.
The things that I like are better than the things that you like!
