My experience is that stuff breaks regardless of brand however a big brand will stand behind it, they put the £ into the R&D for new stuff. I couldn’t say if they ride better/worse as I never owned Chinese brand.
My carbon rim experience;
I had some older Zipp 303s and they were great to ride, the rear hub had the usual load of Zipp lateral play which was well know for that age hub (8-10 year old now). The rims and hubs were nicely made/machined and felt quality. I had a crash in a crit, ruined a tubular and a spoke pulled through the rim however the rim stayed complete and intact.
I have a set of Enve 65s and the brake track developed a pulse after a stage race with a mountain HC descent, new set provided FOC and the replacements been good for over 2 years now. Internal spokes and the holes are moulded not drilled into the rim.
It’s up to you to weigh up the cost of buying a branded rim vs a Chinese own brand and if you think they are worth the cost difference.
For just solo riding and group rides I would possible ride an open mould Chinese rim but for competitive riding and hard bunchies I’d go branded. Don’t want to have a component fail and bring myself or a load of guys down.
