Is the wind more powerful than the sea? Does the house picked up by the tornado have more compliance than the house burnt by the fire?
I think some sprinters look very graceful and some look very dynamic and powerful yet on closer inspection both are very powerful and graceful.
I am assuming you're using the metaphor of wind for Moriteru and sea for Tissier (which I really like btw). Forgive me for thinking less poetically but the way I see both is Moriteru seems to be able to blend effortlessly with his uke; his uke almost becoming an extension of himself in a way. There is a beautiful harmonization between them. With Tissier, I can see better where he is taking uke's posture, breaking his balance before executing the technique as well as demonstrating where atemi fits into Aikido, two things as a practitioner of Aiki-Jujutsu I can relate to, as the two principles are very important to good AJJ.
