Good morning. I have had both and would recommend the USB port just because of the ease of use once you figure out what you are doing. I also find it much easier and in the long run really cheaper. If you ever have a card reader go bad or one of those little cards, then you may be kicking yourself for not going with the USB. Also, USB is more up to date. Good luck in picking out a machine. I am happy with my brother quarttro that are starting to show up on-line as slightly used...I am sure it is the economy, not the machine, but watchout with the brother warranty...original owner clause.
