Hello Wes and all,
I tried here Multipsk versus Mixw at -9 dB of S/N in RTTY 45 (I have not
TRUETTY but they seem to be equivalent).
I tested with a text and the Multipsk decoding was better than the Mixw one .
However, in RTTY the ITA2 set of character is used so it is difficult to
compare
Patrick, thank you for your kind note.
I discovered, as you have known for a long time, that testing RTTY is not
easy because of random figures/letters shifts. As you said, a single
inappropriate shift can mess up a lot of characters! That makes the
statistics difficult.
My test text file is

Hello Wes,
I saw the test file. It is nice except the long suite of figures, which
could be a cause of possible systematic failure (with many errors following
a first error) . Better would be to keep only the call
