Is the overall uptime really worse? (I'm really asking, I don't know the answer to that question) Overhead wiring is more prone to failure, but faster to fix -- a car knocked down a power pole in my street, in a few hours, the utility replaced it with a new one and strung up new wires. In contrast, a construction crew drove a pipe through an underground power line near work, it took nearly 2 days and a street closure before they restored power. Much of california is prone to earthquakes, I'm not sure whether overhead or underground power would fare better in a quake.
