When I saw Jared the first time years ago I found him a bit obnoxious. Looking back, it was his early years, starting out, wasn't as polished, trying to make a mark with his personality, etc.
These days I don't mind him so much and I think his videos give a good, hands on, real world usage test. It's a good balance of covering the specs and being technically while delivering the intangibles, stuff you can't read in the spec sheet, namely how it feels and performs in a real world situation (7D2 at the hockey arena was the first time I said, "I don't hate this guy"). I don't get too hung up on him missing Canon lore/history/details. I actually enjoy the fact that he's not a Canon shooter/expert as his first impressions are more genuine and balanced.
Tony has a good thing going for himself and I have a lot of respect for what he's accomplished. Again, I'm not a huge fan of his videos but he adds a lot of value, especially to the novice who's looking to learn. He gets bonus points for not being a one hit wonder co-wroting a bunch of technical Microsoft books years ago.
Kai and DigitalRev, well they provide some of the least amount of useful info, they certainly produce some of the most entertaining videos.
The hardware reviews are fine, but the camera is just a tool. Personally I enjoy videos that cover on location, the shoot, working with the client, more the business side of things. Zack Arias has some solid videos in this regard. Of course some of his best stuff I think is paid content.
I'm not sure if this customization was in the 5D-III:
