I have a fondness for Super Best Friends Play, if only because their personalities and interests remind me a lot of the friends I had in High School. Their best videos are usually the ones regarding games they're passionate about and want to share, like the original Nier, or any given Resident Evil game.

I'm also quite fond of Beard Bros, I watched a ton of their early stuff, but I kinda fell off after a year. I'm enjoying both of their current Sonic playthroughs, so I enjoy them still.
