My dad said the same rating Bert over Frank Swift. Of the two, I only saw Bert but rate him as the best not just on ability but for his influence on the game. At a time of mudheap pitches, goalies would hoof the ball as far upfield as possible. Bert preferred to throw the ball more accurately to a player to retain possession, almost as far up as the half way line but usually out wide where there was more grass.
Bob Wilson, successful ex Arsenal goalkeeper, coach and tv pundit from the 1960's 1970's was inspired by Berts style, especially through his bravery diving at players feet to retrieve the ball.
I'd put Ederson as number 2 because of his influence in shifting the role of the goalkeeper from solely a shot stopper to outfield player defensively reducing shots at goal and offensively starting attacks. Football has changed. Not long ago de Gea was lauded in some quarters as the best shot stopper in the world but has not found a club since leaving ManU at the end of the 2022/23 season.
Others ranked in order would be Swift, Corrigan and Hart. All three were a dominating, big physical presence in the way of Peter Schmeichel, all in the mould of a traditional goalie from the days when they wore green woolen roll neck jerseys and laced, leather case balls were in use.
