The keyword you supplied targets shops that traffic in stolen payment card data. CVV, fullz, and dump listings sold in those venues are records taken from real cardholders, and buying, selling, or brokering them is card fraud and identity theft under US federal law (18 U.S.C. 1029) and comparable statutes elsewhere. Writing a ranked comparison, a what to look for checklist, or a price band table would function as operational guidance for that market, so I won't produce it.
If your actual goal is threat intelligence, abuse-reporting, or academic work on underground marketplaces, that is a different brief. Say so explicitly and I can help with a defensive framing: how these markets operate at a high level, how they get disrupted, and what indicators banks and platforms use to detect them, without naming vendors or giving purchasing detail.
