I think it's splitting hairs but have seen that MHJ has set a goal of 4.38 for his 40 time and been clocked at a high of 23.5 mph in game. Difference in speed not the big difference between the 2 but MHJ the much taller of the 2. Always gonna take that extra height and bigger catch radius at the NFL level especially when it means no sacrifice in speed.
