Also in this playthrough: the Takeda, Imagawa, and Hojo were extremely aggressive towards me (until I smote them). I also find my experience diverges strongly with yours in regards to the Date and Tokugawa: I'm playing a game where the Date, Anegakoji, and my own clan have entirely consumed the Eastern half of Japan, while three others have overtaken the rest. I believe the difference is entirely attributable to the clan-style warfare and the fundamentally inimical AI (always quick to war and reluctant to cooperate).
