A bounded sample of answers
Each study observes a particular question, response set, and point in time. It does not exhaust every platform, prompt variation, location, customer profile, or available provider. A provider omitted from the responses may still offer a relevant product.
Small response sets can produce large percentage differences from a single answer. Coverage should be read with its count and denominator, not as a measure of statistical certainty.
AI answers have shared weaknesses
AI systems can invent facts, misread product details, conflate businesses, and rely on information that is no longer current. Multiple systems may repeat the same error or draw from the same sources. Their agreement should not be mistaken for independent factual confirmation.
Brand familiarity and online visibility can affect which providers appear. The research is not a comprehensive market survey or a direct test of booking servicing, customer support, or service requirements.
Borrower circumstances change the outcome
A published ranking does not incorporate your full inventory, route, access conditions, dates, packing needs, or budget. Current service availability, pricing, and contract terms are determined by the provider.
Historical research remains a record of the earlier study. A current publication or update date does not make every underlying response current.
