Just be careful in mixing the "best one at teaching" with the "best one at the level of detail and correctness". One is good for aha moments, the other for going into research. Depends on your needs. Similar to the question of "what is the best language to learn?". Depends on your needs.
If I remember right, Apostol uses a non-standard sequence (integration first, then differentiation). That probably only matters if you might be using a different book for another part of the sequence, though.
