In two short text files, maybe typically a few dozen lines in total (and the OS installer is likely to give you good defaults) it sets up all preferences, from command-line keyboard layout to TCP/IP to what settings DJGPP need to compile C++. There is no control panel or other annoying settings GUI to hunt for settings, just two files.
One can be considered lucky if the GUI allows the export & import of settings.
The DOS PC was really clunky, inferior, and a struggle to use compared to any of the alternatives.
At the time, I was really annoyed I couldn’t convert my DOS knowledge into Unix (Linux) shell commands - when need came.
Also not true for FreeBSD and GNU/Linux GUIs.
Unfortunately doing the same kind macros in GUI is a great deal more error prone.
As for CLI vs GUI, both have their places. I wouldn’t say I preferred on over the other except for when talking about specific tasks.
I’ve also been careful not to state “TUI”. Frankly I don’t see much value making a distinction between GUI and TUI in this type of conversation because they’re ostensibly the same paradigm.
