Do not get me wrong, I love Wikipedia and I think it is the best place on the Internet to do basic research, but I would not trust it in this case. Supposing that is where you got the idea that Indian steel was the best.

"What is the best" type questions are very difficult to accurately answer. Wikipedia is the last place I would go to for such a complex analysis. I would not even trust other more reliable sites. Seriously, these types of questions are difficult indeed. Everything has its own advantages. Therefore it is hard to tell whether for instance Panzer IV Ausf. J or T-34/76 was better. I would check numrous experts opinions beforehand.

All that aside, I also actually believe that Indian steel was the best. There aren't any other good candidates for the best steel makers during the EB period anyway.
