Both HDMI and Cat.6 Extender runs on TMDS, active repeater boosts voltage to increase SNR of coz, but cable construction wise Cat.6 cable is no better than any HDMI cable in terms of twist rate and EMI rejection, absents of shielding.  I would also wonder if Cat.6 cable gives comparable bandwidth as typically they're specified to 250 MHz.  Otherwise HDBaseT shall have no limitations either.  Workmanships affects a lot to the electrical characteristics and signal integrity.
