If you liked the "functional" style of calculus in SICM, or want a calculus only book in this vein I recommend Baby Spivak: https://en.wikipedia.org/wiki/Calculus_on_Manifolds_(book)

(And obviously Functional Differential Geometry by the authors of SICM)

Certainly Gerry Sussman's frustrations with ambiguous notation were a big reason for his decision to create SICM! https://youtu.be/arMH5GjBwUQ?t=236
