Using a logically compelling adjustment formula that completely ignores whether steroids were taken, or any other extraneous factor, Hammerin' Hank Aaron comes out on top:

Basically, the formula does this:The Mag's Player-Era-to-Era Translation leaderboard.

Under this analysis:Were steroids behind the widened gaps? Probably. But if we put every player into the context of the league average and leader, we can avoid all the hysteria surrounding performance-enhancing drugs. Let's simply suppose that when Mike Schmidt led the NL with 36 home runs in 1974, his total represented the greatest extent to which any player could have dominated the league that year, and let's say the same thing about Ruth's 60 in 1927 and Bonds' 73 in 2001. For the sake of comparisons, it's the gap between the league and the leaders that really matters, not the possible reasons why the gap changed.
For example, in 1999 Sosa hit 63 home runs in 712 plate appearances, or 8.85 dingers per 100 PAs. The NL average that year was 2.86 per 100 PAs, and the league leader (McGwire) hit 9.83. Thus, Sosa filled 85.8 percent of the gap between the league average and the league leader. For the purposes of this comparison, let's translate Sosa's performance to perfectly average conditions. Since 1920, the start of the live-ball era, league-average hitters have averaged 1.94 homers per 100 plate appearances, while league leaders have averaged 6.60. That gives us a difference of 4.66.
To calculate Sosa's adjusted total, we start with the historical average rate: 1.94 home runs per 100 PAs, which comes out to 13.8 homers in 712 PAs. To that figure, we add 85.8 percent of the difference between the league leader and the league average. In this case, 85.8 percent of 4.66 is 3.99. So, at a rate of 3.99 homers per 100 plate appearances, Sosa would hit 28.5 jacks in 712 PAs. Now add 28.5 to 13.8 and Sosa has an adjusted total of 42.3 round-trippers, an impressive but not historic number.
We don't have to argue about Sosa's training methods, or about expansion or population growth or whether pitching has improved or declined since the good old days.
When we run the leading home run hitters of all time through the PEET system, it becomes clear which sluggers' numbers were inflated or obscured by varying dominance. Translated to an average environment, Ken Griffey Jr., Sosa, Alex Rodriguez and McGwire all drop off the all-time top 10 list, while Mel Ott, Reggie Jackson, Schmidt and Ted Williams move onto it
Rafael Palmeiro really takes it in the ear under the adjusted system! Just more proof to me that the adjustment has strong validity. :awe:The unadjusted all-time home run leaders.
Barry Bonds 763
Hank Aaron 755
Babe Ruth 714
Willie Mays 660
Ken Griffey Jr. 630
Sammy Sosa 609
Alex Rodriguez 609
Frank Robinson 586
Mark McGwire 583
Harmon Killebrew 573
ESPN Insider Link.These graphs here, which compare how Schmidt and Rafael Palmeiro (one of the biggest losers in our calculations) performed relative to the average and the leader in their careers, should help illustrate how PEET works. Palmeiro, who at times early in his career hit fewer home runs than the average, loses 90 home runs via PEET, and Schmidt, who was consistently close to the league leader, gains nine.
