So what's the difference between this and a GXP BB? It's functionally identical.

They are not.
The Sram axle is stepped, which causes the nds bearing to take all the axial load, causing it to wear out quicker than the ds one.

I know the difference between a HT2 and a GXP BB; I was asking why a HT2 BB with an added GXP sleeve and wave washer would last any longer than a GXP BB
