Trying to compare is a losing game. Everybody has the same chance of recovery. Even the best specialists cannot make sense out of why some do better than others.

I am very sensitive to minor head bumps but I recover from each minor head bump within a few days. I don't even consider these head bumps to be an issue. I know that focusing on them will only make matters worse. I bump. I acknowledge the bump, " I'll probably pay for that." and I get on with life. If I have headaches or other symptoms, I just attribute them to the bump and know they will pass. I then move on with my life.
