Actually it feels the opposite, yes Law can use all of these abilites, which make his df better, but each of these guys pose a better ability than Law. Law need room>cost lot of stamina, these guys above can perhaps even use it nonstop without wasting many stamina, use it better since it fit to their fightstyle, as example Burgess who pose the power ability.
Have it mind these 3 above perhaps just got it new(based on Law statement in this chapter) and they will do even more skills with the new df in the future. And if Law hype them so much, saying no wonder why their bounties keep increasing, then you know they are pretty strong, in fact Law try to not face and fight them(he would still beat them in my opinion).
Burgess is in my opinion above guys like Jozu.
Also I have high hopes for Law vs Teach next chapter, lets hope Oda not skip that fight.
when there's the Corrupt king/Demon sheriff
