I had indeed read an Osprey book about the Sherman, pretty good I think, which gave me a very good insight of the tank and ist bad reputation.
I think that, rather than its armour and gun, the problem with the Sherman was its high profile and the narrow tracks, which made the 25-ton tank to have a pressure on the ground of about 900 grams per square centimetres, whilst the Tiger I & II, weighing 60-70 tons, had a pressure of 750 per square cm!
