There is 2 square taper standard:

-ISO (njs stuff, campagnolo..)
-JIS (most shimano stuff etc)

If your ride heavily an ISO crank on a JIS bottom for years, it's normal that it fail. The square isn't exactly the same, and don't allow the crankarms to go on correctly..

Using SG75 BB & Campagnolo BB combinated with SG75 since years without issues

Maybe newest BB are stiffer, but GXP bb aren't revognized for their longevity

This is also myth. I've used the same GXP BB for nearly 4 years, 5 days a week, all weathers. Its getting slightly gritty now

I've seen plenty of GXP bearings died due to salty winter slush in Montreal (not only GXP I admit) or due to overtightening, maybe it fucked up my opinion..

I would love to try Omnium with CK or hope cups and Zen chainring, this should be ace
