George,
I agree with your anecdotal assessment. In considering an auto-tuner, I
expected the Palstar, due to its design and construction, to be the clear
winner on all counts. That is why the results of the comparison surprised
me.
I'm glad it's working great for you.

Well I have the Palstar, the LDG 1000 and the MFJ. I
just wonder if anybody looks inside ham gear any more.
The Palstar looks like a 1.5 kw tuner, but neither
the LDG or MFJ look like they can handle power .
There is a vast difference between the Palstar and
both the MFJ and LDG.
The MFJ and LDG are lumped parameter designs using
relays to switch components, while the Palstar uses a
large inductor and capacitor with stepping motors.
So yes the Palstar is slower, but it has a wonderful
memory algorithim. The relay clanking in the LDG and
MFJ works, but you better use low power to tune or
else you will be buying relays.
Sure I read the articles but the are many factors that
need to go into a buying decision.
I will just end it with these thoughts
I use the Palstar at the output of my AL-1500. It
will trim SWR at that power level. The other two will
not even do that.
Additional antenna position...Who needs that....I use
an external multi-position antenna switch, with one
position used to ground everything...just in case..
which is how the station is left when I am not in the
shack
