There really shouldn't be any sound difference if the connectors are high quality. That said if you have to rearrange your set up at some point the XLR's make it easier to extend your cables in a pinch.
I ended up going with some bulk Mogami cable with Neutrik connectors. I can solder pretty good. It really is amazing how much cheaper it is to buy in bulk. I was dumbfounded at Guitar Center's prices. I usually wouldn't put it past them to have high prices, but man they were ridiculous.
