Hello, lovers of Nikon! I'm searching for advice! I want to change my old Olympus mirrorless camera. I' d like to choose between these two Nikons https://cameravs.com/Nikon-D750 and https://cameravs.com/Nikon-D800E Who has one of this, is it good enough? Thanks

I have a D750, and it's enough for me.
