Which are better for my HDMI cables? Ferrite Cores or Net Jacket?

Im looking to buy a HDMI cable from monoprice.com and they had the Ferrite Cores and the Net Jacket HDMI cables, i was wondering what the difference is between the two. Which is better?

The cheapest 6-footer they sell works fine for me. It's DVI>HDMI, but I'd think the HDMI>HDMI version would perform similarly.
