Actually if IM is caching to disk, then I would think that in that case distort SRT may be faster, especially if you turn off EWA color lookup and go to fast interpolation lookup (which is typically good enough for most un-scaled rotations).

Also note that if you plan to do this a number of times converting you input image to MPC (disk memory mapped) format first, and using that for input can make the task faster by removing the need for each individual command to do that disk cache conversion each time you run it.

This is one advantage of IM. Fine-control of the image processing.
