Yes, very better.
My experience says:
1) this coma corrector has relative low tolerance. For example: I can not reduce from 83 mm to 80 mm, because of filter well. But the performance with 80 mm is better than 83 mm. I have some reflex because of this plus 3 mm. Despite of it works with plus 10 - 13 mm. My telescope is f/4.9, so less critical than yours.
2) I percept that always there is a side of the photo with less performance. I thought that it was by bad axis optic centralization. Your photo seems to have the same appearance: the right side is better then left side. Exactly like mine.
If this is true... don't worry. It's the same with me.
