Front or Back wall diffusers

It is recommended that the wall behind the speakers be reflective in nature, so that the sound develops properly. On the contrary, the wall located behind the listening position should be absorptive, so that the rear reflection of the sound does not interfere with the perception of the stereophonic image.

Weird how you seem to answer your own question.

This is my point of view and it makes sense, but other people think differently and have diffusers on the rear wall. I would like a greater consensus and be sure to get the best result.

I use Anthony Grimani's acoutic recipe and have pics posted in my profile, see the diagram below. He uses combo panels on the front wall and you can see how he stagers treatment on the backwall:

Example of a combo panel:
