Oh, don't get me wrong, they look ugly, which is why they were never repeated, but they're fundamental to the silhouette saying "this is the TOS
Enterprise." Even the ST09
Enterprise used them. It's one of the most distinct things about that version of the ship. Heck, back in the day, looking at 32x32 or 16x16 pixel icons, the nacelle pylons were the
only visible difference between the TOS and movie-era
Enterprises. Even when I was playing with shapes trying to TOSify the Discoprise just a little more, I still gave the main pylon a taper, and included the potato-peeler aft strut to evoke the sweep back without actually sweeping them back.

If they wanted to make ships that looked good, they should've set DSC post-TOS, but they didn't. I'll be just as perturbed if, in the Picard show, they show the
Enterprise-D and it doesn't have that horrible top-heavy double-wide saucer. If they said, I don't know,
D.M. Phoenix's Allegiance was the retconned Galaxy-class, yeah, it'd look better, but it still wouldn't be
right.
