ISB ~ Matthew 11 v11

no one greater:John is the greatest OT prophet (11:9). In the New Covenant, however, even the least NT saint outshines the most illustrious saints of old. These prophets looked ahead to the New Covenant but did not share fully in its blessings (13:17; 1 Pet 1:10-12). Jesus thus contrasts the Old and New Covenants; he does not undermine the saintly life of John (CCC 523, 719).
