Need an option od "neither" because my answer to this would be "Good lord no..."
Assuming Fultz goes #1, I'd take Tatum or Ball over Gordon/Saric all day, every day.
While dropping to #4 is possible, the probability of that happening is so incredibly low that I'd barely even bother preparing for it.
Gordon's potential is pretty limited - he'll never be a star. Saric's potential is probalby higher, but I still don't think he'll be anything that special. Tatum could be a major star - sky high potential.
