Tamers12345 is the Yang to CWC's Yin; the balancing masculine force of light to counteract Chris's dark feminine element. He's also the only one I can immediately think of that's endearing, but that might be because unlike a lot of cows, he really does visibly put in work. Say what you will about the quality of his videos, but you can watch his channel go from "I want to make sonic animations" to having an 80 minute long animated movie and several hours of content produced. He's demonstrably improved, at the thing he likes doing, ironic or not.
I guess the next closest one of the threads I keep up with is Doug Walker. He doesn't really seem to have gotten better at his content necessarily but he seems to have a self awareness about the absurdity of his fortune. The worst his council of traitors could come up with was that he was bad at making content, which is rich coming from Linkara/Lindsay/etc. Otherwise he's just pretty inoffensive.
