No, I said that there can be differences, not that there have to be.
Anyway, your screenshots shows two things:
1. CherryBoyz didn't remove the padding, leading to an unncessary increase in filesize and far worse
2. CherryBoyz's video is oversharpened, introducing very noticable ringing.
Based on those screenshots, OZC is likely closer to the source and definitely of higher quality. The thing is, CherryBoyz's video is damaged compared to the source and anyone that actually does prefer to have things sharpened to that amount could easily use post-processing on OZC's video.
To see the ringing, look at the black lines used in the two persons. It's especially noticable where their hair touches the mecha and around the back and shoulders of the guy.
Last, but not least, it seems CherryBoyz messed up the chroma - there's a noticable shift when compared to OZC and the later seems to have more natural colors. To determine with certainty who messed up the colors, you'd have to compare the videos to the BDMV, though.
