The Buran shuttle itself, otherwise, is quite similar to the U.S shuttle, it is, however, more advanced in the sense that unlike the U.S shuttle it can be piloted unmanned solely by computer, completing even complex two week missions with no-one on board.
To summarise... Buran-Energia was in many ways an improvement on the US Shuttle system, with a much more flexible design, even if sadly, it is not the system that is currently in operation.

There are some awesome pictures over there though. Like this one.
