I just finished watching JonTron's videos, what now?

So, I got into Game Grumps as a fan of egoraptor. Some friends said "check these guys out" and I put it off for a while but eventually got into Game Grumps. And I loved them. And I kind of fell for Jon after a while (in a admiring kind of way, like, he's a really great and funny guy) so I decided to watch all his videos. And I just finished all of them up to the latest. And now I wanna know whose videos to watch next? I'm torn between ContinueShow, PBG, and The Completionist, as they're all kind of part of this closely-knit youtube gaming community family so I'd like to eventually watch all of them. Which do you guys think I should watch first? Thanks in advance. :D
