I beg to differ....
The stock recovery can only flash firmware signed by Asus and perform some crude wipe operations.
With a custom recovery you have way more tools at hand to fix problems:
You can wipe or format partitions selectively
You can take nandroids and restore them
You can check the integrity of file systems on partitions
You can fix permissions
You can flash SuperSU, custom roms and more
Some have a build in file manager allowing you to move data off the tablet even if it doesn't boot anymore
Some have a build in terminal you can run commands from.
The list goes on...
But sure - you have to do all of the above including flashing the custom recovery correctly
or you can seriously damage your device like you did.
I am really sorry that you lost your mainboard and had to buy a new one, but don't kid yourself: It was not the custom recovery damaging your tablet. It was you...
