That's why I said:

A .pdf will be included and won't have its quality diminished by inclusion into a .pdf generated directly by pdflatex.
It's more efficient, it's more direct, it's simpler and it's elegant (in the sense of scientific correctness).
When you make a .pdf from a pixel file, set the compression appropriate to the file's content --- that's part and parcel of making ``a good quality file''.
When you make a .pdf from a vector image, ensure that the vectors / Bézier curves are preserved (and that the image is not converted into a pixel file) --- that's part and parcel of making ``a good quality file''.
