Is `Split-WindowsImage` or `Export-WindowsImage` with `SplitImageFilePattern` better?

Description

I'm not sure whether using the Split-WindowsImage cmdlet or the Export-WindowsImage cmdlet with the -SplitImageFilePattern parameter is better. I need to test this and determine if there is any difference.

Split-WindowsImage

This is a dedicated cmdlet for splitting an image into .swm files. However I'm unsure if it does any sort of optimization or cleanup like the Export-WindowsImage cmdlet.

Export-WindowsImage

This cmdlet is for exporting images, and with the -SplitImageFilePattern parameter it can create .swm files. However it also explicitly states that it optimizes images during export:

You can also optimize an image by exporting to a new image file with Export-WindowsImage. When you modify an image, DISM stores additional resource files that increase the overall size of the image. Exporting the image will remove unnecessary resource files.
