Edgar is actually a very good comp. If Votto finishes up strong he should finish with more HR, R, RBI, H, and SB, and a very comparable career wRC+ and fWAR. He's also played about three times as many games in the field as Edgar did in his career.
Votto has 6 AS games and Edgar has 7
Votto has an MVP, and Edgar has his two batting titles
Neither is likely to win a WS and both are likely to spend their entire career with the same team.
They have very similar cases if Votto can finish his career with a few strong seasons.
