A very 'general' answer is that coax will have less 'variable' loss
from being near stuff than 'ladder-line' because of the way it's
constructed (and why it was originally made anyway). If that's the
only consideration you have to think about, then it's a fairly simple
question to answer. When you start thinking about the other
properties/characteristics of coax/ladder line, the answer isn't quite
so simple any more. (I like using ladder line, but I seriously doubt
if I try running it in a vehicle, see what I mean?)

I've found that a 10ga loaded with small shot will clear out most
leaves that might interfere with ladder line. Large twigs, limbs,
etc, require larger shot. Gotta get that angle right though, that's
the hard part. Not to mention the neighbors...
(No, I'm really not that dumb. Just depends on how frustrated I am.)
