I see Enma like a faster car, but you have to get used to it 'cause it's harder to drive, if you push the accelerator pedal it just boost you to the sky, difficult to manage.
From the beginning, Zoro's first attempts were exaggerated, it drains too much Haki and power and you can't control it properly.
Zoro had to train to control this Haki boost, the sword tends to overshoot. Now, instead, he's not unleashing all his power and its quality, he has to find some equilibrium.
I put it simple: if now we could exchange Enma with Shusui, with the same new trianed Zoro, the attack wouldn't be as strong as those coming in the next chapters.
There's nothing wrong with it, Lewis Hamilton is the best F1 driver nowadays and he's winning also 'cause he has the best car. Having a better car doesn't bring discredit, instead only the best can "tame" Enma and in this chapter all of us have witnessed what is Oden level, the former Enma owner.
Credits to Zoro, he had a power up that only the best can benefit from
