Default SWR losses in 300 ohm TV twinlead vs coax

I have installed a 135 foot dipole which I tune for all bands but 6
and 20 (I have dipoles cut for those bands.)

Well, one of the locals and I were discussing a loop antenna. He
insists that the loop is better fed with 65 feet of 75 ohm coax and
then 50 ohm coax to the tuner for the radio. I was saying there would
be less loss by using a 300 ohm twin lead since it was being tuned for
all the HF bands and 6 meters, with open wire or ladder line being
better options. He insists that if the loop is properly made, it is
better to feed it with the 75/50 combo which properly matches the
antenna.

any thoughts?
