I want to subscribe to either Vcp or Beckett and would like feedback from users if possible.

1. Which service has a more thorough database for managing inventory/valuation?
2. Does Beckett pricing come from real sales or still from survey?
3. I collect lots of different cards including significant non-sports. Do they both have pretty good checklist data for n series non sports?

Thanks for any help!
