Well, despite his high achievements, Napoleon was quite a miserable person (according to his appearance and complexes). Looking on the David's painting, we can see the brave man filled with courage, who points up his finger towards the sky, showing he's ready to reach the victory whereas in the Delaroche's picture Bonaparte is portrayed like exhausted man with desperate and sleazy look. The main point is that he's not a superman, he's just a MAN, so Delaroche's painting is more realistic because he treats emperor as a normal human with its lacks.
There are several things that make Delaroche's painting more realistic. In the first painting, it seems as if he is riding toward battle in the Alps, when in fact he was not, as the description stated, Austrian forces had already been defeated, so there was no reason for him to look like that. In Delaroche's painting, he seems more accurately depicted, cold, tired, and with others (most likely servants) who are forced to walk while Napoleon rides on his horse.
