I'd enjoy it more if the author actually tries to dig the story from Kirito's perspective, but not using that 2-dimensional view like "Oh no, I messed up." It's hard to describe, but probably it's more of psychology? The original fails to make Kirito a rootable character. Feels like the only reasons he's the MC are because:
1. He is a Beta tester
2. He has a harem
3. He has the experience
Oh, and I forgot to say one thing. In the original, the MC suddenly becomes OP and it resembles those crazy solo players in typical MMOs but here I get that feeling that the MC is nerfed every once in a while. In some chp, he acts like he's your average gamer, and in some other chapters, he acts like he's one of those crazy gamers
