I think that immanence as formulated by Spinoza allows us to think about reality in the making without referring to abstractions and allows us to think our immersion in the world

Wdym?

I really like the way Hegel reads Spinoza (on immanence and his analysis of "Omnis determinatio est negatio" in particular) and for Deleuze the way he reuses Spinoza to talk about the plan of immanence in anti oedipus, as well as his reading of Spinoza, which is great.

I can understand but i think he's great and i really like the way Hegel and Deleuze reuse it (in their own way)

No it's great
