Here are some EV/PP stats for the five players who starred from 1955 to 1967. This should provide some additional information about the players, the roles they played, and the context in which they scored their points.

Geoffrion played a major role on the great Montreal power play, playing the point. He was the top power play scorer of his era.
He only scored one shorthanded goal, confirming that he rarely killed penalties.
At even strength, he was a very good scorer, but others were better.

Bathgate was an excellent even-strength scorer, probably the best in the league during his peak. He played the point on the power play, but didn't score as many points as Geoffrion - possibly because he had a weaker supporting cast.

Mahovlich was an excellent even-strength scorer in the first part of the decade, but he was never a top power play scorer in Toronto. This may have been because the Leafs had one of the weaker power plays in the league, even as a great team. Their power play scoring was more evenly distributed than other teams, and it seems likely that Imlach didn't put as much emphasis on the power play as other teams and coaches did.
I divided Mahovlich's years in the 60s into two in the summary, as he was significantly more effective from 1961-63 than from 1964-67. Bob Pulford, not Mahovlich, was the Leafs' top EV scorer from 1964-67.

Bathgate was the top even-strength scorer over this time, but Mahovlich was a close second. Mahovlich also scored noticeably less on the power play than the other stars of the time.

Pilote was the top scoring defenseman of his era. No surprises here.
Tim Horton

Horton was remarkably consistent. It appears that he played a minor role on the power play, but was not a major contributor there, never breaking double digits in power play points. At even strength his point totals are good, very consistent, and are as good as any non-Pilote defenseman of his era, as seen in the table here
here.
