A clearer starting point for your choice
Asking different AI chatbots the same shopping question can produce different answers. BestForThis puts their recommendations side by side and combines them into an Overall shortlist, so you can see the common favourites and compare alternatives.
How products reach the top
We use each chatbot’s main top five. First place earns five points, second four, and so on down to one point for fifth. A product outside a chatbot’s top five earns no points. Every chatbot has equal weight in this main score.
We add the points for each product. More points means a higher Overall position. Extra suggestions mentioned outside a chatbot’s main list do not count. Different names for the same product are combined where the identity is clear; different products from the same brand stay separate.
What happens when products tie?
- More recommendations wins. We favour the product appearing in more top-five lists.
- Then we compare the best position. A product reaching first place beats one whose highest position is second.
- Then we use chatbot market share. We multiply each chatbot’s points for the product by its share of chatbot website visits, then add the results. The larger total wins this final tie-break. If products are still equal, they share a rank.
Market share is used only to separate otherwise tied products. It does not make a chatbot’s advice more reliable. Our current inputs are ChatGPT 56.4%, Gemini 25.0%, Claude 9.6% and Grok 2.3%: September 2026 global website-visit shares from Similarweb, reported by Visual Capitalist. These figures exclude app and API use and are not UK-specific.
Use the ranking alongside your own needs
“Most recommended” means strongest support across the answers we compare—not a guarantee that a product is best for everyone. Check the features, size, price and suitability that matter to you. Chatbots can make mistakes and may rely on the same sources. Our comparison is not independent hands-on testing.
Prices and regions
Recommendations relate to the region shown in the header. Prices are dated snapshots from linked retailers, not live quotes or promises of the lowest price. Check the retailer for the current price, delivery charges, availability and pack size before buying. Product photographs may show different packaging or sizes.
What you can check
Our sources and comparison notes record the answers used, calculation details, market-share inputs, image credits and known limitations. We identify gaps in the information supplied rather than inventing model versions or collection dates.
The current edition has no paid placements or affiliate tracking links. Buying a product does not change its ranking.
