I am not judging them as far as critising them, I am making observations about them and forming opinions. Both men are vastly more experienced than I am and are superior martial artists. I am just interested in comparing and contrasting their techniques and understanding why they are different.
Effectiveness. As they are both very experienced and know they are expressing 'martial' then perhaps the basis of your comparison needs a little tweaking.
Assuming they are both equally effective martially then you would be left with a different question.
Basically...'Why are they both equally effective martially?'
