Would this be the same using Disks or is there a special use?
It is an alternative to 'Disks' but it works slightly different.
'Disks' dumps the complete content of the ISO 'as is' in the USB-stick.
So whether a stick is bootable, or what partitions or filesystems it ends up with, depends completely on the ISO.
UNetbootin has some extra tricks, for one: it carries its own bootloader (SYSLINUX) and its own filesystems and can therefore be a bit restrictive sometimes, but a saving grace in some other scenarios.
One step further is Ventoy.
A Ventoy prepared stick can contain a lot of ISO's at the same time.
Instead of 'burning' the iso to stick, it's just simply copying the ISOs as files.
I Have one Ventoy stick with about 17 different ISO-files
When I boot the stick, I'm greeted with a menu with 17 OSs to choose from 
But to get back to the solutions:
a big "me too" here: I also always use 'Disks' to "burn" my ISOs
