Now, one of the deficiencies here has been examples. Try this: "best miter saw". you will not find any websites that actually discuss the answer to this question, despite it being a product category with a lot of price variability and performance tradeoffs (weight, capacity, power, cord vs cordless, accuracy).
Nearly any product reviews for large purchases follow the same pattern unless consumer reports has decided to dig deep (e.g. washing machines).
How about guitar strings? Sandpaper? Printers? google's algorithm has allowed profit motivated websites to displace the commons to too great an extent.
