Marquez is a good candidate, Dela Hoya achieved a lot also if you consider him to be from this era, Dela Hoya has a very good resume, e.g. Genaro Hernandez, Ruelas, Leija, Pernell Whitaker (very close), Felix Trinidad (robbery), Shane Mosley (robbery), Quartey, Campas and of course Vargas, plus he gave a prime Floyd Mayweather a competitive fight when he was older.
