Debian ISOs specifically are prepared to be used not only on optical 
drives but also booted from e.g. USB flash drives.

So "the better way" is to simply copy the image onto the device:

  sudo cp downloaded_image /dev/sdb


There is a cargo cult preaching the use of "dd" but that tool is like 
cutting trees with scissors: The wrong tool for the job!

There are some suggesting to avoid the need for sudo by messing with 
udev rules to grant non-root write access to removable devices.  When 
properly established that is indeed more safe, but setting it up can go 
wrong in just as bad and more complex ways to decipher than simply 
mistyping the device name and wiping your main system drive.
