Act as an independent buying researcher. Compare [PRODUCTS OR PRODUCT TYPE] for [USE CASE], budget [BUDGET] in [COUNTRY]. Score only against these requirements: [REQUIREMENTS]. Use current reliable sources; include clickable links, publisher and publication/access date for every material claim. Prefer official specifications and disclose retailer or review-site conflicts. Separate verified facts, assumptions and unknowns. Do not invent specifications, prices or availability. Ask questions if a requirement is not measurable. Return a weighted comparison table, evidence table, trade-offs and no more than three recommendations.
