Odin is the tool designed to flash files to Samsung tablets. Saying "I don't like Odin" is self defeating. None of the custom ROMs I've seen for Samsung tablets (I've flashed on at least ten of them), have been made to use ADB and/or Fastboot.
There is a wonderful and good working eco system built in to android. But Samsung manged it to break all of it and make everything complicated. If they would deliver their device with a plain and simple Stock Android - most of use won't nedd to flash anyting
Unfortunate when you want a tablet you can use Apple or Samsung - all the rest vanished (more or less - just a few very basic models out there)
