Sheesh John. For someone who has been in the business this long I should expect you to be answering this question.

I would strongly recommend PDF. The PDF filters are more current and more reliable. And PDF files are for the most part interchangeable with Adobe Illustrator.

EPS files can contain both text, bitmaps and vector objects. They are intended for printing and not for editing. EPS files are typically "placed" in publishing applications such as QuarkXPress or Adobe InDesign and output to a postscript output device or converted to film negatives for the creation of printing plates.
