IAP generals

Here's how I would rank them now with Oda Nobunaga's library chapters added:
Uesugi Kenshin/Battlepass (still the best!)
Oda Nobunaga
Takeda Shingen
Sanada Yukimura
Tachibana Ginchiyo 
Ii Naotora

Nobunaga's new skin seems really good to me, and his library chapter takes away one of his biggest flaws on release, namely the lack of a library chapter. Thus I believe he's jumped up to second instead of below the cavalry generals. I'm still an ardent Ginchiyo fan, but I'll admit she's pretty weak in comparison to Nobunaga and Masamune, unlike Shingen and Yukimura who both are pretty much the cream of the crop for cavalry. If you're so inclined you can choose to hold off of Yukimura if you feel that three IAP cavalry gens are too much.

For you with Shingen/Kenshin, I'll recommend Nobunaga. He's definitely reclaimed the spot for best teppo gen, he's crazy when on odzutsu handcannon, and he hits really hard with multiple hits in both of his skins. But in reality, they're all very good generals, and the initial analysis still holds pretty well. So get whatever you want!
