Tamiya kits are beautifully engineered with almost bulletproof fit and finish. Tamiya USA customer service is very good as well. They were very responsive on an occasion when I broke a part while removing it from the sprue tree. However, there is something to be said for the Revell kits, especially when considering they do the older vintage vehicles, muscle cars etc.
I have found that once you get used to how each company organizes its instruction sheets, they will then become easier and more intuitive to follow.
