IMHO, it should be a LOT more preferable.

Whether you go overhead or underground is a personal issue.
208Y/120 is much safer than 240 Delta, especially when you throw in
the wild leg connection to get 120 service.
Sounds like you live in an area where security lighting might be an issue.
Better to have a light mounted on a utility pole than the house IMHO,
but then again, that is a personal issue.
208Y/120 anyway you can get it.
Underground has a lot to offer, especially when it is time to sell.
You might be able to negotiate with the utility, but I doubt it.
After all, whether overhead or underground, there are costs involved.
