Methodology
Brand verdicts are based on buyer fit, build quality, support path, price pressure, and the risks that tend to show up after delivery. A strong reply from a manufacturer can improve factual clarity, but it does not improve placement.
If support coverage, warranty language, or dealer access are thin, we would rather say that plainly than hide it behind marketing copy.
