Dixie Dean (may or may not be biased) for me.
32 goals in his debut season for Everton, fractured his skull at the end of the season in a motorbike incident before scoring 60 goals in the following season.
18 goals for England in 16 games, including 2 hat-tricks.
390 goals in 447 games.
Also, he was hard as fuck:
Whilst at Tranmere, he was on the receiving end of a tough challenge which resulted in him losing a testicle in a reserve game against Altrincham. Immediately following the challenge, a teammate rubbed the area to ease the pain. Dean shouted "Don't rub 'em, count 'em!"
