Well, going off of the comment by the person in chapter 11, our version is "cleaner, easier to read, and with better tonal wording", plus we also do more SFX. It's fine though, I know we are not a well-known group, so it's tough to "compete" against popular groups like Reaper.
(What I mean by this is that readers tend to be overly judgmental toward lesser known groups and often blindly support bigger groups simply because of their popularity. This can also be seen between Asura and Reaper. Even though Reaper is a big group too, and has better edits and translation for this manhwa, a lot more readers still read Asura's version because they are just way bigger. You can check the like difference on the chapters on Comick site)
