Yeah I am honestly having a hard time telling which which is which haha.
The upper part shows a little better detail. Do you have Cavity turned on for your viewport? Maybe bump it up a little, perhaps do Screen Space and World Space.
I personally like a screen space set to 1.5 for ridges and valleys on my own stuff but that is just me.
The lower model of the two with a faint blue tint is hard to read any fine details on. I wonder what the improvement in poly count is between the two.
