I prefer it being present

To be honest i’d prefer it to be there at all considering the current trend of removing it.

But to answer your question, jack on top, so when the phone is plugged in the wall you can stay on the other side since the headphone cable wont be bent

I just want the phone to rotate correctly whichever way I choose is up. I want to be able to read ebooks and charge my phone without holding it up. /End rant

Same side as the charging port. All cables must come out at the same side.
