I do not know whether Acrobat is better. But Adobe is quasy standard for printing companies. And Acrobat gives me more confidence that my document corresponds printing demands. If file size is 5 times smaller, it is not bad either.

I find nothing wrong in using multiple softwares. e.g. Photoshop can also 3D. But I'm doing it in 3D program. Because it is precieser, better and faster. Is it bad or good?
