If you have a large nose, middle partings will draw attention to that (hence why I normally go with a side parting), but a parting too far to the side looks ridiculous, i think just off centre looks nice and natural
I always had a side parting growing up cause I had a fringe. One day I just decided to part my hair in the middle, I had to keep manipulating it to stay in place at first but after a while it just stayed there.
