He has a touring bike, they tend to be fitted with rather more robust

My touring bike has had Panaracer Paselas for many years. When one good
friend died, I inherited a Pasela with some extra flat protection -
maybe called "Tourguard" or something? (I forget, and I'm not home to
check.) But I don't think I've mounted that one yet.

 
Even so they would be thicker casing than the Gatorskins plus more tread...

 
I don't know that's true. I've used Gatorskins on our tandem for years.
I never noticed any great difference in tread thickness between the two
types of tires.

 
<https://www.bicyclerollingresistance.com> says 3.6 mm vs 3.2mm for the
casing and another 1mm or so of tread? They do seem though to have same
weight, clearly they are much thinner than a Marathon or similar.
 
But I?ve never used the Pasela, though I have used the Gatorskins if quite
a long time ago now!
 

 
But admittedly, the tandem is a very different sort of beast.
 
 

Fair bit more weight and load on the sidewalls I?d guess!

If you're going to mention Schwalbe Marathon tires, you need to
specify which one. There are several and they're all different.

Not that different, the standard Marathon is that a standard normal
Marathon, some with variation in tread design but broadly quite similar,
 
There is the Plus variants of which I?ve used two out of the three tyres
namely the Marathon plus and the Marathon touring plus, both are fairly
similar in use, both can cope with some mud on a path, but are overwhelming
by even quite mild amounts. ie the tread can?t clear I?d expect the MTB
variation to behave similarly for similar reasons.
 
Even gravel bike tyres tend to be less drifty and clear better.

There is no "normal standard Marathon" tire.  Most of the Marathon
tires are quite different from each other and perform differently.

 
<https://www.schwalbetires.com/Marathon-11100150> there are minor
variations in tread patterns such as the marathon green, or racer, as a
range it?s quite homogeneous with the main difference in behaviour being
the plus versions have a harsher ride, due to stiffer sidewalls.
 
The tread is all fairly closely packed and almost entirely cosmetic, my old
Commute bike which used to have Marathon tour plus tyres which has more
substantial tread than the big apples but behaves the same off road, in
that though the blocks are deeper they are still closely packed and so
squirm on mud as they can?t get mechanical traction, and have no ability to
bite in gravel or wet grass etc.
 
Very different to say MTB or Gravel tyres which can have quite different
characteristics despite looking reasonably similar.

It's not aboiut the tread, which is cosmetic for roadbikes. It's
underneath the tread that makes them different.

 
The carcass is same across the range, with the difference being the plus or
non plus versions mainly that the plus versions, have a much harsher ride,
something I’m glad to report that the One plus the roadie line with plus
doesn’t suffer from.
 
Is I think a version with Addix (mildly racier compound) but very much
still a good hybrid/commuting tyre with different styles with minor
differences, note even off road the tread because it’s close packed makes
little difference.
 
Much bigger difference once you step out of the family to stuff like Big
Apples and the like, though they are still hybrid commuting type of things
but they have much more supple ride etc.

It's the layer under the tread that sets them apart and makes them
perform diferently. Schwalbe calls it the protection level, and it has
a big effect on performance, not just in puncture resistance, but in
rolling resistance. The "plus" versions with the heavy layer are
slower enough for me to have notices, and the lighter layer on the
Racer tires are sigificantly slower than the Green Guards according to
my tests on asphalt.

Yes how a tyre deforms under load gives it’s rolling resistance plus
potentially some tread though this is with MTB tyres, and to an extent
Gravel tyres.

Yes the plus variants are slower, though as either the protection layer is
interacting with the carcass and or the sidewall is different, they the
Marathon and Marathon touring in plus variety have fairly awful ride
characteristics aka very harsh.

The non plus versions are well just normal for the type, the Big Apples
have a more supple feel as they have lighter sidewalls, not as supple as a
Gravel or road tyre but supple for the type.
