If they offered more subject matter that appeals to me, I think that I would prefer Tamiya due to their quality, engineering and fit. I LOVE Revell and Revellogram kits, but I SINCERELY wish they included build options in their kits. (wheels, tires, aftermarket high performance engine parts, etc.) That being said, I have purchased, and continue to purchase, more AMT and MPC kits than the other brands.
