Answer could be in what will this 72mm -75mm lens be used for?
Here are all three lined up for size comparison. The 72mm SAXL takes a 95mm filter, 75mm f4,5 Grandagon takes a 67mm filter, 75mm f6.8 Grandagon takes a 58mm filter and is very compact.
The 72mm SAXL has a bit more contrast than the Grandagon of the "N" mc vintage. 72mm is used on 5x7 as a extreme wide and this is not a "common cup of tea" for most. This focal length on 4x5 is considered a very wide angle lens producing quite exaggerated near to far perspective, this effect is much greater when the 72mm is used on 5x7. For this group, the 75mm is used on 6x9 as a moderate wide.
Is the 72mm worth the extra cost over the 75mm f6.8 Grandagon, only if the extra image circle size is absolutely needed IMO.

How about the Fuji 75mm SWD f5.6 with an IC of 196mm
Do not have or ever used the 75mm f5.6 Fujinon SWD.
Do have the 65mm f5,6 Fujinon SWD, it is GOOD. similar to the Grandagon in contrast overall performance. It does have a slightly cooler color rendition when compared to the European brands. Otherwise, there is little wrong with the Fujinon f5.6 SWD series.
If the 75mm f5.6 SWD Fujinon is being considered, the 75mm f5.6 Schneider Super Angulon needs to be considered.
Suggest, if the larger image circle of the 72mm SAXL is not needed, pick one of of the 75mm wide angle lenses, try it and from there. Most are can be purchased for a small percentage of their original cost today. It really comes down to trying out the specific lens for your n=image making conditions and needs to figure out which of these choices meets your needs best.

My copy of the Grandagon N 75mm 6.8. is small, light and SHARP! I love this lens on 4x5.

75mm is a short focal length for many 4x5 view cameras. As previously mentioned, FFL is about 79mm which is the distance from the front of the lens board where the lens is mounted to the Ground Glass to focus this 75mm to infinity. If the Bender cannot collapses this far, a recessed lens board will be needed to sink-in the lens on the front standard to meet the required Flange Focal Length for focus at infinity.
If the Bender's front and rear standards are so far collapsed that a recessed lens board becomes mandatory using the standard/conventional bellows, camera movement will likely be impaired significantly. The common solution to this problem is to apply a bag bellows to allowing the front and rear camera standards to move with ease with both standards close together.
