always used square taper bottom brackets when possible (when doing self builds), so that's is a lot of bb's over a lot of years.
built a new tourer a couple of months ago, used a un26, which I know is cheap but usually ok, it died in 6 weeks
fitted a un54 about 3 week ago. feels loose already and squeaks/creaks like buggery.
finger is poised over the buy button for a new xt m780 set up
