Hi Joe

One good thing about the ladder line antenna is that it can be used on any 
band, and in any portion of the band.   You didn't say how long it was, but 
with most antennas, as you go up in frequency, you start getting gain with 
the ladder line antenna.  An 80 meter dipole fed with ladder line becomes 2 
half waves in phase on 40, which gives you some good gain.

With the coax fed antenna, you are limited to certain spots on the band 
whereas with the ladder line fed antenna, you can move from one end to the 
other and the antenna will still be efficient.

I have 2 of those twin lead fed antennas here and it gives me lots of 
flexibility.  I like 'em.

P.S.  by this time next week this thread will have nothing to do with what 
you first asked :-)
