Multivariable calculus book recommendations

I would like some recommendations on multivariable calculus books.

I already have Susan Jane Colley's "Vector Calculus" and I am planning to get Marsden's book as well(mainly because I can get it for free).

I am not completely satisfied with Colley's book for a few reasons, the main one being the lack of rigour in certain points ( previously I worked through most of Spivak's book and that was quite a transition as far as rigour is concerned).

Any further recommendations?

Solution 1:

I recommend Hubbard&Hubbard since it has some sophistication that might be appreciated after becoming acquainted with Spivak, but also does not adopt the same ultra-rigorous style.
