Just the opposite. Hoad was Laver's idol. Like many of his era, Hoad's backhand was his stronger side and was a lethal weapon. His heavy topspin, continental, wrist flick forehand (that Laver copied), coul be a bit erratic by comparison, as was Laver's.
With all due respect I disagree. I will preface this by writing that I never saw Hoad in person and I have only seen him in numerous videos. However I have read in a number of accounts that Hoad's steadier side and stronger side was his forehand. However that's besides the point because I don't think his backhand is among the greatest.
Rosewall, in his description of Hoad's game hints that Hoad's forehand was the better side-"His forehand was always good and as he grew in confidence and experience his backhand became almost better."
Here's description from Ellsworth Vines' excellent book "Tennis Myth and Method." Overwhelming, sometimes erratic court dynamo, whose career was cut short by back injury. Uses Australian grip on all shots. Crushing first serve. Wrist of steel lets him hit shots beyond the capacity of the normal human being. Forehand steadiest side, but backhand equally severe. Amazing strength, acceleration, and moves. Rarely varies pace and gives to lapses of concentration."
Here's a quote from Kramer's book "The Game." Hoad had the loosest game of any good kid I ever saw. There was absolutely no pattern to his game. I'd marvel at the shots he could think of. He was the only player I ever saw who could stand six or seven feet behind the baseline and snap the ball back hard, crosscourt. He'd try for winners off everything, off great serves off tricky short ball, off low volleys. He hit hard overspin drives, and there was no way you could ever get him to temporize on important points. Segura went crazy just trying to get him to lob a little more."
I never see Hoad's backhand or forehand among those discussed by experts as among the greatest strokes and I think the reason is clear. While Hoad could do virtually anything with either shot, he was just too erratic on both sides for either groundstroke to be ranked with the best ever.
He had too loose a game although he did tighten it up somewhat in the Pros.
However I do think it's possible that you could say that Hoad's backhand or forehand, when he was on his game may have been the most dangerous groundstrokes in history.
