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.
Try reading your own post out loud, get out the rubber duck if you need to, and see if you can understand why you sound like a deranged zealot rather than simply a passionate user.
I'll help you get started: note that every argument you've made starts with a base assumption about your interlocutors pulled from nothing, and note that every assumption conveniently draws a stark dichotomy between you as the informed rational party and the other as a bumbling uninformed moron.
Also notice how you draw lines in the sand that let you completely dismiss any thought you don't like.
