Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.
Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
Quick verdict
The review evidence points to a tradeoff: adaptive sync performance and stand adjustability versus build quality and Screen coating clarity. Choose according to which strengths matter more to you; the overall score alone does not settle that choice.
Choose LG 27GX790B-B for adaptive sync performance and stand adjustability.
Choose LG 27GX790A-B for build quality and Screen coating clarity.
Scores are out of 5. Missing scores mean missing review evidence, not a missing feature.
