Yes if you only care about 2d bbox detection, a smart bounding box annotation tool has some advantages. If you need to solve 3D vision tasks, as is the case in 3D bbox detection, 3D keypoint detection, 6D pose estimation, then you need a tool that can also label the z dimension.

Ok, sure. I was just focusing on the 2D detection task, since that seem to be the focus of the linked product page.
