Just because a product's review is stellar and garnered many accolades, doesn't translate to the best-selling product. Most people (I included) look for something that is affordable (within reason, of course). Just because the color gamut is perfect or the response time is second to none, doesn't mean I will get it discarding all my other options.
If it's affordable and good then there's no harm in getting it.
The difference between "enthusiast" level and an ordinary person's view is minimal...and non-existant with the rest of the people.
But of course, those with lots of money to burn, will blindly buy the product that has received the most excellent reviews irrespective of the difference. If it's rated at 95%, they would forego the 90%rated product at half the price.
And the "best bang for the buck" is still far off from affordability.
