Long term will depend on how you maintain them. When you drag these things down the road, at 60+ MPH, things are going to come apart. Doesn't matter who built it.
Either trailer will serve you well, as long as it has propper maintenance.
One area I would be conccerned with, is the tongue weights and what you're towing with. The manufacturers are advertising both trailers as 1/2 ton towable. However, both of these trailers have "dry" tongue weights at or above 1000 lbs. There are many 1/2 ton vehicles that don't have the payload to carry that kind of tongue weight.
