It all depends on the context of course. But, I like using the guide tones, in the case of C => E & Bb, to resolve in the next chord (if possible)
For example
_ _ _ C7 [ F _ _ _
Could be played:
_ _ _ Bb | A _ _ _
Or simply:
_ __ _ E | F_ _ _
Maybe even:
_ _ _ E | A _ _ _
or even:
_ _ _ Gb | F _ _ _ (substitute dominant is Gb7)
But there's nothing wrong with
_ _ _ C | F _ _ _
