DJT has played Bojutsu before, but not Shaolin, IIRC. I think it's a new experience for him to play Shaolin and, thus, not as crispy or natural as Slayer is with the character.
IMO, DJT plays Jin more defensively and patiently than Slayer does, who conversely seems to prefer a semi-rushdown gameplay. On one hand, DJT has knowledge of more optimal combos and on the other hand, Slayer's more on point with the conversions. It's definitely interesting to see this contrast between their gameplay styles when it comes to Jin.
