The main thing I like about this manga is the story, I LOVE the art that yusuke Murata does, but I'm reading the original webcomic:

And the art is atrocious, but I'm reading every chapter, getting ahead in the story and it's so captivating I can't help but read, and then get excited about how exactly it's going to be retouched by Murata. Sure, I hate that he wastes pages on beautiful artistic drawings, but I understand the necessity it's like comic to manga filler. And I've noticed that Murata doesn't get full of himself either like in the Meteor crisis, when it switches to a comedic moment he tones it down to match the mood.
