Opinions needed

[*Z*]

Backstory: I had made my MIL a rainbow block granny square afghan years ago. Of course it got destroyed in the fire.
I am going to make her another one as a surprise to replace it. The last one I made was solid color blocks for example one all red block, one all orange block etc. I had them in a diagonal rainbow patter when I sewed them together.
I was thinking for this one of doing granny squares again BUT I was going to make each block rainbow. What I would like opinions on is should I make all the block with the same rainbow pattern (red in the center, then an orange ring, a yellow ring, a green ring, a blue ring and finish with a purple ring) OR should I do each block in a staggered pattern ( the first block with a red center and such but then the next with an orange center and ending with a red ring on the outside and the next a yellow center and ending with an orange ring on the outside etc.) ?
I'm not sure of how I want to do it yet.
Any thoughts?

I like the diagonal rainbow idea, myself. If I were going with multi-colored squares, I'd make the last row of all the squares the same color for cohesive appearance and to make the other colors pop.

Maybe some of these pictures will prove inspirational for you:

The one I had made previously was like the 4th picture (only I didn't have any variegated)
