I'd say generally that it's going to boil down to personal preference and whatever makes your printing easier.
The wild cards are the ambient light and the surfaces you'll be bouncing off.
Another option you may consider is using gels on the flash gun(s). If for example you are using a nikon speed light in "A" mode this can get you better exposures because the flash gun measures it's own output rather than the camera. The flash gun doesn't "see" the filter.
