The notion of being unbiased is absurd.
People forget/were never taught that the reason a newspaper covers both sides of a story isn't because of Journalism. It's because back in the day, instead of paying one guy to get one side of a story, and a different reporter to get another, services like the AP realized if they bought/sold one story with both sides, they'd make more profit.
You want bias in reviews. They aren't scientific observations. You want to take data points and have them run through a human brain.
in my business, we do huge amounts of testing (tested 12 SUVs this very morning) to get numbers like 0-60, quarter-mile, etc.
Now, if numbers were all that mattered, we test a top fuel dragster and declare that it's 3.2 second quarter-mile run at 347 mph makes it "the best." Of course, because we have biases, we might say something like, "Don Garlits' car is real quick, but it's hell at the mall."
Likewise with cigars, when someone says, "Tastes like chocolate and bubblegum," you then want the reviewer to say, "And that's a disgusting combination."
Now, LYING about a cigar (or a car) is horrible. Always tell the truth.
