Both Buran Ghati and Rupin pass are located on similar altitudes -- Rupin pass is slightly higher. The terrain and landscape is also similar. In fact, the Rupin pass is placed on the same range and aerial distance between the two pass shouldn’t be more than a few kilometers. Choosing one trek over the other is a personal choice. We don’t prefer Buran over Rupin or vice-versa. You shouldn’t either.
