It's actually exactly the opposite case. Any method to copy data from one location to another will work, such as by using dd, or cat, or even just formatting the drive and using cp. If you don't want to deal with command line tools, there are many GUI tools that are literally just a couple buttons to press on all major operating systems. My personal preference for GUI liveUSB tools is Balena Etcher, or Fedora Media Writer. Both are incredibly easy to use and feature intuitive GUIs. There is no "mystery" or "arbitrariness" surrounding it at all, it's a pretty straightforward process. Copy data from one place to another and you're done. The only differences between the methods, as the previous comment said, is the speed of the transfer and some minor things that the end user has basically no reason to think about.

As far as its ease of installation and use goes, my tech illiterate father was able to install and use Linux Mint with zero problems and has been using it for years, so I'd say it does a pretty damn good job overall.
