I tend to use some of these "modern" tools if they are a drop-in replacement for existing tools.

E.g. I have ls set up aliased to eza as part of my custom set of configuration scripts. eza pretty much works as ls in most scenarios.

If I'm in an environment which I control and is all configured as I like it, then I get a shinier ls with some nice defaults.

If I'm in another environment then ls still works without any extra thought, and the muscle memory is the same, and I haven't lost anything.

If there's a tool which works very differently to the standard suite, then it really has to be pulling its weight before I consider using it.
