Let me add another opinion.
Tuners might permit your transmitter or receiver to "like" the antenna
impedance
a bit better - but they do not help an antenna that does not radiate to
radiate better!

This will be an interesting thread!!!
My Dipole interest is for 80 and 40Meters, I have a beam for the other
bands.
At this QTH I have tried (all in an inverted Vee configuration, hung off the
tower):
A 40-80M trap Dipole with balun
80M Dipole with homemade open wire line on standoffs (fed by a real balanced
tuner, not a 4:1 balun)
A G5RV (no balun) and T-match tuner.
The trap Dipole was terrible.
The open wire line was a pain to deal with, but worked OK. The plug-in coils
in the tuner were a nuisance.
The G5RV was the best.
For the 80 and 40M part of my 5BDXCC I used the G5RV and a Butternut
Vertical
At 80-40M coax losses are negligible. I saw no difference between the coax
to ladder line G5RV and the open wire line Dipole.
Let it begin.......
