Chiming in late on this one...

Mythical attributes aside, I believe the real reason that ladder line
has become more popular is:

1. Almost all rigs are All HF band these days.

2. Many people have just one antenna they can put up at any given time.
Whether it is space considerations, maintaining a low profile or
keeping the XYL happy I remember the discussions with my wife when I
wanted to put up the HF vertical. "Why do you need two antennas?" "Are
you going to transmit two signals at the same time?". Twasn't easy, and
a lot of Hams might lose that argument.

So assuming it is a doublet, and I wanted to run 80 to 10 meters, I'd
put up much wire as I could, not mess with coax, just run ladder line to
a window panel, then into the house, into a tuner that can handle
balanced line. And pay attention to the lengths that might make for
trouble in matching.

Or, put up as much wire as you can, put an autotuner at the feedpoint,
and run coax back to the shack.

probably a six of one, half dozen of the other, depending on what you
already have, what kind of support structures you have (if you are
putting up an inverted V, then supporting the weight of the tuner isn't
an issue..), etc.
