Koufax was better than Drysdale.  Here's something interesting: against right handed batters (RHB) Drysdale was dead even with Koufax in On Base Plus Slugging (OPS) averages against them by opposing batters.  PA is plate appearances against them.

Koufax had no platoon advantage.  Which meant that switch hitters had no advantage against Koufax, I think mainly because Koufax threw overhand.  Drysdale was just the opposite, a tall sidearmer.  Drysdale was really tough on RHB but no tougher than Koufax.

Here is some anecdotal data for six RHB, 3 LHB and one switch hitter.  Frank Robinson and Billy Williams are listed, not (Jackie or Brooks) or Ted, none of whom batted against Koufax or Dyrsdale in the regular season.

It looks like Koufax had a bit more trouble against these top hitters.
