It was the Germans who named the Sherman “Tommy Coocker” and the English who named it “Ronson” this was with the crews experience in North Africa and Italy it was also common to have survived more than 1 Sherman some had survived 5 though not entire crews, in 1943 the Sherman was on par with the PzIV but then the German put a longer barrelled gun in in the PzIV,F2 this changed things as the PzIV could destroy a Sherman from greater range.
Germans used trains as much as possible to transport tanks, this is less to do with reliability and more to do with saving benzene, benzene the Germans did not have and a Panzer division with over 150 tanks uses a vast amount of fuel to travel 100km the Allies would have done this also except the railway lines had been destroyed and when they did repair lines tanks went by train as far as possible, modern tanks are also transported as much as possible by train does this mean they are also unreliable.
As for interlocking road wheels well yes it was not the best design on a Panther this along with torsion bar suspension latter used in Pershing (I wonder why) gave a Panther over 36cm of travel giving the tank a very stable gun platform a Sherman on the other hand only had less than 18cm of travel giving a very rough ride this would also reduce the speed across country, a Panther could neutral steer within the tanks own length a Sherman required 2-3 times this space, Panther had wider tracks and was able to travel across soft muddy fields without much trouble a Sherman with its narrow tracks would simply bog down , the top speed of a Panther when first introduced was 55km/h this was later dropped to 45km/h and in 1944 to improve reliability more and also reduce the amount of Benzine used it was reduced to 32km/h while off road was 24km/h now if we look at a Sherman we find that official top speed of first generation benzene powered tanks was 40km/h for a short distance while sustained speed on a road was 32km/h first generation diesel engine Sherman had a top speed of 51km/h a T34/76 was 52km/h and 40km/h off road so we see that a Sherman is nothing like the Ferrari we are constantly told and T34 was faster both on and especially off road.

Panther was never available in the numbers Sherman was it did have its problems it was not as reliable as Sherman its transmission was not strong enough for the tank and required a long time to replace one major factor most people choose to ignore is that the German were on the retreat and as such did not control the battle field thus could not recover and repair tanks lost one only has to look at the figures for destroyed German tanks to see how they were lost most being destroyed by their own crews or abandoned this doesn’t mean they were a bad tank.

Israel had an arms embargo on them and still does for things like tanks hence why they make their own, the Sherman they did buy were being given away by 1967 Sherman was long considered not worthy of front line service by any nation certainly by 1944 it was considered obsolete Israel had no option to have Sherman and the one thing that they did was copy what the British did and put a longer 75mm gun in the turret and replace the engine with a more reliable Diesel engine the fact is the French supplied the 75mm guns these were exact reproductions of the German 75mmL71 Panther gun which in 1967 was still a potent weapon, as proven in many conflicts both before, during and after WWII superior tactics can win the day even when faced with technically superior tanks
