Zero centered Diffs vs. Raw utilities

Hello,

could someone guide me on the choice of outputted utilities to be used (Zero centered Diffs vs. Raw utilities) in case the objectives are:
-re-calculating total utility per winner combination per respondent
-determine preferences using (exp transformation of total utility) respectively to each combination across respondents ?

Hope these few lines are clear enought to understand the context,

Many thanks in advance for any feedback,
