They're both trash and pieces of shit on the same level. No one's better or worse. Both should krill themselves and then Taeui and Yuri could be together.
Canonically, between Xinlu and Ilay, Xinlu is mentioned to be more scary and dangerous. I understand coz after taking up Ilay dick on his ass just because, I fear Xinlu have nothing to fear lol.
and I thought ilay was worse than xinlu!
