Several methods to write ISO to flash drive

This is what I've found so far:

1. dd if=FILE-NAME.iso of=/dev/sdX bs=1MB && sync

2. balenaEtcher
3. usb-creator (it is in the repos)

4. curl -L https://git.io/bootiso -O
   chmod +x bootiso
   bootiso -d /dev/sdX FILE-NAME.iso

5. Rufus
6. Unetbootin
