I tend to favor the guys that are on the forefront of the industry. Obsessed Garage, and Ammo NYC are great for that. They feature individuals like Jason Rose, Kevin Brown, Michael Stoops, Mike Pennington, Jason Kilmer, Andy Ward, etc - who not only seem like stand up personalities, but are legitimate entities in the industry, whose work is innovative and cutting edge.
I also really love Forensic Detail. Out of all of them, Jon has the most endearing personality, and is very objective despite his preferences. Also, he has great expressions, and a penchant for humor.
Junkman2000 is another one I visit for old times sake. Another humorous guy.
Apex and Dallas are ok. Their biases kind of leave a bad taste though. I have to reduce it to a difference in philosophy and approach.
Car Craft is pretty good, very impartial, but also a very, very different approach to polishing in particular. These guys have me wanting to make video tutorials of my own, but I just hate the camera....
