Chris Allen, hands down.
DrYoYo understands the business, the products, and the people behind the hobby.
His reviews are always outstanding. He employs great photography, easy to understand linguistics, and journalistic integrity in everything he does.
When something new comes down the pipe, and I know the reviews are soon to be flowing like water, I wait patiently for that update to his blog I know is coming.
So, Ben, that’s my $0.02 for what it’s worth.
Edit: Inb4 Chris displays modesty.
Huge Afterthought Edit: It occurs to me that a lot of people feel the same way I do about Mr. Allen’s work. It also occurs to me that quite a good number products he reviews he pays for out of pocket. If you are in the business, getting your product into Chris’ hands would be a great way to obtain both constructive criticism and promote your product to the masses who place their trust in his words. Food for thought.
