The best selling point is an end-to-end purchase flow that you don't have think about at all, it does the price comparisons for you. However, if you want to use it to just get the list of top candidates and compare and go make the final decision yourself I'm sure it can do that for you too. Either way I see a future where these claw-like agents can fit into everyday use cases.
Maybe... if run locally with full transparency into the prompts (including system etc) and independent benchmarks for the models (i.e. tests on how eager they are about selling me stuff)
But even in this hypothetical world I would still have a hard time teaching an LLM what I find important in a product. Not everything can be captured in easy to compare numbers. "Does the device creak under pressure?", "What's the one weirdly unergonomic thing about it you only notice after weeks of using?"... Stuff like that. Things which are easy to miss even if the model ingests all relevant reviews about the product, because it might not stand out, but might be important for me.
