Is there an actual advantage to BBP vs SBP?

I’ve looked at Dr. Diff and if I decide to complete the conversion I’ll definitely go with his products. I’m just asking if there’s any kind of added structural integrity, or anything else I’m not considering.
The axles are claimed to be stronger, I have had good luck with them.
Also he has different set up so I was able to use big bolt pattern 7.25 backing plates and all the brake hardware when I changed out my small rear for a 8.75 so the cost got cheaper real quick.
