Sure, for a lowest-common-denominator, GUIs and websites will let you use a mouse. That's great for if you want to use a tool & don't want to take time to get familiar with it.

There are some things which are inherent to GUI or CLI interfaces.. but, overall, nothing ensures a TUI will be good, and nothing prevents a GUI from providing a good interface. -- The distinctions are generally going to be program specific.

So e.g. using openlens (GUI) vs k9s (TUI) vs kubectl (CLI).
