I agree that once learning how to use dd programs like BalenaEtcher sort of become more clutter than anything else.
Still, something I would always prefer over dd is Ventoy, simply because not only allows me to easily make an ISO bootable, but allow multiple ISOs to be easily bootable on the same USB stick. I hope it never becomes abandonware.
While I agree that dd can be easily used, it still is a dumb command (as in its only purpose is to write and nothing else), which can result in some issues regarding validating the integrity of the installation, at least for a beginner.
Furthermore, it can be disastrous if you don't pay attention to what you type in, as it will happily overwrite anything you type in.
Also, I don't think that dd alone should be used as a backup, as it might result in inconsistent backups. The best simple backup system, no matter whether you are a beginner or an expert, are snapshots, and maybe using dd to backup those to an external drive to be sure.
