I've had good luck with LX,XT and XTR hubs-don't really see any reliability difference.
I also have s set of Hugi 240 hubs/wheels- they seem ok also-pricy, but actual wheel weight within grams of the XTRs of 8 years ago.

The only disadvantage is they aren't integral type bearings(built in races). What we call sealed bearing are idiot proof- the loose ball bearings are tricky to adjust.They should have lower rolling resistance and be very slightly lighter. It is possible to destroy a sealed bearing while installing it-yes, I have done that on a motorcycle!
