Too many implant quotes

I am comparing All-on-6 Dental Implants for maybe March and my head is full now. One clinic sent a very neat price table in 20 minutes. Another asked for panoramic x-ray, photos, smoking history, and said they need to check if temporary teeth are possible the same week. The second one feels slower but maybe more honest? I am not asking which clinic to choose, just wondering if others felt more trust when the coordinator did not give exact price immediately. I also need to understand deposit rules because flights from Manchester are not cheap if plan changes.
