Flat Ethernet cables are often more convenient than round cables, as they take up less space and provide added flexibility when organizing wiring. They also perform better than round cables on shorter runs due to their superior durability when bent or manipulated in tight spots. However, at longer distances, it becomes a different matter; round Ethernet cables can provide better protection against crosstalk which is important for intensive network activity. Although flat cables can still be used for longer runs, rounded cables are preferable because of their superior reliability in shielding against interference. Because of this, many professional or commercial installations use the round type of cable instead of the flat variety. If speed and efficiency are your goals, then opt for the round version of the Ethernet cable.
