The Enterprise D (the one shown int he OP) had a good reason for the wonky shape; it was effectively two different ships in one, able to separate into two combat capable ships One was a saucer and the other included the warp drive.

Although this was usable for coordinated attacks, another use seemed to be that all the most dangerous parts of the ship which were the most likely to fail catastrophically and destroy the ship were located in the lower section (such as the warp core), so in case of an emergency the saucer could be used as a large escape shuttle.
