Silvers Rayleigh is also skilled at using Conqueror's Haki. In an SBS, Oda stated that Rayleigh would have knocked out all 100,000 Fish-Men, meaning that his control was superior to Luffy's.

After the time skip, he started using it on purpose. On Fish-Man Island, he knocked out 50,000 of Hody’s crew with one glare, showing he’d gotten the hang of it under Rayleigh’s guidance.

The most noteworthy members of the Roger Pirates were Gol D. Roger, Silvers Rayleigh, and Scopper Gaban. As the captain of the crew, Roger was the strongest and the most influential crew member.
