im saying that IDEALLY, on a madreiga that we all should strive for, a madreiga few ever reach, a madreiga described in the Chovos ha Levovos and many other places, yes your personal preference (translated: a stronger taivah) should NOT be a factor in the choice unless you choose the sandwich associated with the stronger pleasure because you wish to increase your pleasure for the sake of being more grateful to Hashem.
If theoretically all other things are equal (which they never are if you think deeply enough into your choices) then perhaps you are right.
Or perhaps one should choose against the sandwich which his taivohs dictate, in order to strngthen himself spiritually via the wonderful Midah of Preishus. This madreiga can be achieved by many, even us little people
