I've been watching The Tek now for about a year and I love it. I really like the format and the discussion that takes place between Logan and Wendell. I really enjoy that The Tek covers Hardware, Science, Games, and NSA.
I have been trying for ages to find its equivalent in other areas such as music, film, or a dedicated games channel.
I have watched a few different ones but my problem is the presenters are generally extremely loud and obnoxious or they use too many bright colours to try and distract me from the lack of quality in their videos.
Check out MKBHD for technology, if you're into art then MarkCrilley is an awesome dude. If you enjoy videos about the human spirit then SoulPancake is here for you. Fancy some cars and mods, than the MotorTrend channel is a good place especially RoadKill, filmed every fourth Friday and a dose of MightyCarMods wont hurt either. Alas for gaming the only channel I watch now that is worth any time is XboxAhoy and his sister channel AhoyXbox.
Forgot to mention Blunty if your the sort of chap who enjoys good Photography and general anime stuff presented in a real high quality manner from a plucky Assie
I use to watch a lot of inside gaming just because those guys are nuts. Machinima had to let them go and now they are part of the rooster teeth family known as FunHause
The Srsly Wrong podcast is pretty good. They cover lots of things generally on the more political side, and bring in some interesting viewpoints, backed up well by their arguments.
I like to think Mine is pretty good if you'd like to see Japan without all the typical overdone weeaboo clickbait and "top 10 things to do in Tokyo" bulldust :p https://www.youtube.com/channel/darcnoodles
