Everyone is unique & has his/her own strengths & weaknesses. so it is quite impossible to say on 2 differ people from 2 differ. backgrounds and differ life stories that one is better. Each has his/her challenges. For one it is to learn 1 hour but the second finds it difficult to learn 4 hours straight….So the premise of the question is that they are comparable which is unequivocally wrong.
TO ANSWER CLEARLY :If 2 people are the exact same (which is not possible) and one learns all day and the other one hour- The whole day guy is definitely better and loftier. Simple calculation. Make more money= richer.
