Hydra does go through bearings faster - specifically the single drive side hubshell bearings but it’s faster to change than it is to remove the axle from a King or P321 hub with zero special tools.
Also, the Hydra system is epically ingenious in terms of the KISS principle. I can’t believe how well it’s survived on my one speed.
