Yeah, Mike improved his singing a lot since Meteora era, but he still isn't better than Chester. Chester sings much harder parts than Mike, Chester parts contains singing at higher, more intensive and longer notes, and he sings much more. What fails Chester's voice now, is that his voice got more hoarse, and he can't hold some notes, for example Faint. He wouldn't be good screamer neither, just look how he screams in Faint. But he would be still a better screamer than Oliver Sykes. What I think is strange in Chester's voice is that, there is some parts that he is almost perfect, while there are similar parts where he isn't that good. For example screams in APFMH vs. Faint.
It's good that you kept being a LP fan, here you won't get picked on for being a LP fan
