lwd, CAC has a good point with the Me262, when it was in the air and in the hands of a good pilot nothing could touch it. It had issues with the engines because they couldn't be constructed fully of heat resistant metals where needed. As such the engines only last 25 hours each before an overhaul was needed. The design was sound however, an engine having been constructed of the proper metals running at full power for over 100 hours non-stop without a single mishap. As for the Tiger, it was probably the most feared weapon of the war and definitely had a huge effect, and as such can definitely considered as the best tank of the war, albeit it is debatable depending on which factors are given the most importance; and that applies to all 'which was best' discussions. One could for example argue that the best aircraft of WW2 was the C47 Dakota, few aircraft having contributed as much to the war effort. Furthermore the aircraft has a sterling record in the areas of capability, reliability & ruggedness.
