I would say the novel, it's more detailed, has a different feel to it as well, the Manhua seems a bit more light-hearted, which isn't bad per se, just not what I personally prefer. The Donghua is worth watching, beautiful animation and music, so far it stays true to the novel although that might change in the future. It's unclear how much of the love story they might have to cut out thanks to China's strict censoring.
I understand why people are puzzled, there are so many characters now and they all look alike, it becomes hard to keep track of them, not to mention their respective places in the story, I'm no longer sure who I have to remember and who is there just to expedite one single scene.
A big cast can be interesting, the lack of distinct features as well as the amount of background characters without a significant role in the story start to overwhelm me, rapid switching between point of views only adds to my confusion. MDZS's cast is much bigger and I never ran into this problem, here it seems I got lost somewhere along the way – it really is a shame because I like the overall plot. Maybe it just isn't made for me.
