You are right: The CM8_Utzinger is much better at longer time controls.

But please again note my already at CCC published objection against playing
Chessmaster.CMP's against each other:

You will have noticed that I do never play CM8_default vs CM8_Utzinger or
similar matches between the various CM8_personalities. It is my deepest
conviction that such trials are more or less a waste of time. At first I have
made this too but soon recognized that whatever settings are used vs other top
programs, the supposed best CM8_setting at a given time control had [like
CM8_default] not much chances against Junior6a or most other top programs.
Furthermore I have investigated about 150 test positions with six CM8_settings
[CM8 default, and 5 others, no Chessmaster.CMP already defined in CM8] only to
see that they all were close together. In any case: with these tests it was
simply not possible to define the best CM8_setting. And funny, Chessmaster_8000
default took second/third place in these tests, the same CM8 which does not
succeed in the expected manner against other top programs. All these tests and
trials confirmed to me that it is somewhat useless to find the top CM8_setting
by let different CM8_personalities playing each other. And frankly spoken, who
in the chess world is interested in knowing that [let's say as an example] the
CM8_Titan [nothing against you Graham!] wins most of the time against any other
Chessmaster 8000 personality. Such a statement does not bring anything if the
same CM8_personality does not obtain fairly good results [at least 50 % is
required] against other top programs like ChessTiger14, Crafty, Fritz6,
GambitTiger2, Gandalf432h, Hiarcs732, Nimzo732, Shredder5 and so on.
