My friend said the author doesn't like the pacing of the other manga (take it with a grain of salt, though), so this one is supposedly following the LN more closely, like a more accurate adaptation of the LN. Elex Media Komputindo just released this version in Indonesia so I bought volume 1. The art isn't too bad but not too great either (although cover of volume 6 here definitely shows improvement than volume 1), panelling looks flat (like someone has said), and it goes more on point than the other manga so it feels faster. As a fan of the story that read the WN, it isn't a bad adaptation overall, but still pales in comparison with the other manga (admittedly my bias takes part as I've read that manga first, but it does have better artwork). It's a good quick read to remember what happens, I guess.
