There are two ways to reduce interference to & from a cable.  Those are
shielding and twisted pairs.  UTP cable, including CAT 6 relies on
twisted pairs to reduce interference.  Unless the twist rate for CAT 6
is significantly more than CAT 5, there will be little difference
between the two for interference purposes.  My understanding is that CAT
6 cable construction is held to tighter tolerances re twist, spacing
etc. to better support higher data rates.  Those tighter tolerances have
little effect on interference.
