I think your question should be like Which B2B Portal Can Provide Genuine Buying Leads, every portal has its USP because of
reach in buyer countries,
focused product categories
its user friendly features etc.
You should be very much clear about your product line and its market place and competition as well.
Don’t guess do some R&D before joining any portal, you should prefer logical decision rather than emotional.
