Nothing is better then experience. 90% of whats being said is "on paper" Im an American so ill go with the Abrams because i believe its the best because its proven itself time and time again. Israel would come in a close second with their merkava MK 3 BAZ becaouse these tanks have actualy seen battle and proven themselfs. People think whats newer and more advanced is better, thats not always true. Countries that constantly fight like America know exactly whats needed for a battle and what isnt. Some of these tanks from other nations are damn nice looking and advanced but tell me, what do they really know about war and what works?
