The delusions are probably the biggest distinction from classic Chris and nuChris. It's actually sad to see his mind deteriorate the way it has. I think the house fire, bob's death, and the troon shit fucked with him more than we realize. As idiotic and silly classic Chris was, he was pretty high functioning compared to now. Classic Chris would've churned out pages if he was both free from trolls and given the money.
I have to agree on the any new comics being incomprehensible Christine-babble, though. If you told me back in 2013 when I first discovered Chris that in a couple years he'd be LARP'ing as an all-powerful CPU goddess and that it would somehow be boring as all hell, I'd never believe you.
