Hi Bryon,
I think your question is a bit too vague for anyone to offer a proper response. In what way would you like the output to be "close to adobe distiller"? You reference a 300MB file size, does that mean you want the PDF smaller?
Assuming you just want the PDF smaller, we have found that large PDF file sizes are almost always due to the images contained in the PDF. In rare occasions it can also be due to font embedding (particularly for Chinese fonts which contain thousands of gylphs). If you have a copy of Adobe Acrobat you can use the "Audit Space Usage" tool to identify which parts of the PDF are too large, e.g. https://acrobatusers.com/tutorials/how-to-audit-and-optimize-a-pdf-file
If you are able provide more detailed information about what you're after, then someone may be able to provide a better response.
