Production tech vs Industrialization

[Dorky8]

I've always researched Industrial first but after this thread would like to see some more evidence. I'll research some of my games for comparisons.

It's minor but it might be interesting to have one country of your alliance rush production still (the ne that benefit the most from it and can afford) to give its major allies a tech bonus later when they can research it too (for example after you reach INF 2, INFW and other utilities warfare and other maxed out research).
