Never had any major issues with Hope brakes. I’ve killed XT,Saint,Deore,HFX9 and recently a pair of Zees (in three weeks a new record!).
They may not be the most powerful but they have good modulation and more importantly are FULLY rebuildable unlike most of the competition.
Any brake can fail but compare the price of new seals for a Hope caliper against the price of a new shimano XT caliper – for me it’s case closed.
