Yes, could be. In the end, it all depends on the situation :)

The difference is, that hash-space and similar schemes operate at
"per-object" level - they can quickly find what objects are near each other.
While BSP and BV-trees usually operate at "in-object" level - it's good to
use BSP for object-to-geometry collisions; but hash-space also gives you
object-to-object collision advantages.
