I have tested hobbywing and meepo (lingyi) hubs extensively with super much load ( 2 grown men)
(To see how, check diywhy)
Meepo 100mm hubs snapped after 2 3km rides.
Axle snapped clean through.
Hobbywing hubs are still going strong and are not even bent after 250 km of 2 person rides at max speed.
If you inspect the design of the 2 drivetrains you will clearly see hobbywing is using the much stronger clamp design and lingyi is using the square fitting method also found on koowheel hubs, which is prone to get loose.
