I would add one more step at the very end.. a feedback/rating question - either simply “Did this help you decide?” Yes or no, and “was it a good/right decision?” Yes or no. “Which one did you ultimately decide”? Or you could add likert scale rating... but I like that you kept the tool simple.

You must have thought about those possibilities. It’s a cool tool/idea!
