CAT5/6/7 cables consist of four 100 ohm twisted pairs, each with a
different twist ratio to minimize crosstalk between the pairs. Indeed,
there is nothing inferior about it as a feedline as compared to coax,
except that it may see its Zo modified slightly if it's laying on the
ground or very close to another conductor. CAT5/6/7 pairs have fairly
low loss.
Bottom line -- nothing wrong with what you're doing. You're just smart
enough to know that it is a perfectly good way of feeding a Beverage.

My experience, I have short BOG with a 230 foot CAT5 feed line. I use it
mostly for AMBCB receiving.
Signal strengths are good, S9+ on night time 1000 mile away stations.
Daytime reception is also good.
But I have no comparison to Coax. My common mode chocking is, "I've been
told unconventional", "probably
doesn't work", however my feedline doesn't pickup AM stations, so if my
BOG has any directionality,
the feed line doesn't alter that.
