I've never seen anyone mention that that voice Oney and DingDong do sounds a lot like Oskar Kakashka from Hey Arnold. I thought that's what they were riffing on but I haven't seen anyone bring it up.
I really liked the chemistry with Oney, DD and Julian but I definitely saw signs especially with DD that he has issues with anyone going against what he thinks is the right thing. Even little things he seemed to freak out about. Then I see he's a perfectionist who hasn't completed a project in a while. Makes sense.
That said their vids always got the most laughs from me. I still watch clips of the Rugrats ones, PAAWWGERSH, Kingdom Hearts, etc. Julian is usually just the sort of audience self-insert laughing at the jokes, but he has some spicy jokes here and there that really made me appreciate him. Especially in the GTA ones. Sometimes it's especially funny because he's usually the least crass one and then he'll come out with some insanely racist joke out of nowhere.
Psychic pebbles and Tomar energy is definitely great though and I'm not really feeling the Cory, Lyle, Adam stuff so much.
