1. You want to pass additional options to tdlmake for a custom preparation (e.g. type of filtering or output data type).
2. The automatic color space conversion for Katana is not satisfactory and a more fine tuned approach is needed.
3. Save storage space as 3Delight will create a separate a texture file for the optimized version. (However, when using the automatic approach, you can manually removed remove the original non-optimized version texture when the optimized version has been done).

Another consideration is if you don't like the delay that will occur at the start of a render the first time one or more textures are used. And you prefer handle that one time optimization process manually and on your own term.
