In keeping with the TC philosophy, I was excited to see this very very tiny and simple usb image burner, which is currently supported and in active development.
The bzt "usbimager" on GitLab
https://gitlab.com/bztsrc/usbimagerIf you miss Core2USB, you'll love this. The fact that a verification step after burn is on by default immediately caught my eye.
The instructions of how to use it, and also comprehensive down-to-earth instructions on how to compile it (if you want to rather than rely on the supplied binaries), for a variety of architectures and o/s, was similarly gratifying.
But, like all simplified "dd'ers", it does what is told in the iso archive itself. Hence, at this current time, it will NOT make a bootable uefi-only stick. But it will work very well on more conventional systems, or those that have legacy/csm features in bios turned on. For that, you'll want to burn a custom stick with directions included elsewhere on the forum.
So far I really like it. Tested with CorePure64 11.1 on my legacy/csm boxes and bingo - a read-only filesystem that you can garner additional tools to perform custom setups to go much further if you like. Or use as-is with external data devices, following the normal rules of how to use read-only live-usb's. You get the picture.
