As a foldable guy, I live in Singapore where Huawei, Xiaomi and Oppo also sell their foldables. They look okay at a glance but walk into any store and try them and the software immediately makes the phone feel underbaked.
There's a reason despite that and their lower prices, there's still far more common to see people with Samsung's foldables than their Chinese counterparts.
It's a form factor where software is even more important though. I'm sure that for some people the larger screen is fine enough but at that price point, the average person needs more value out of that cost. To each their own but it does seem that it's not as clear cut as YouTubers may make it seem. There's also the fact that Samsung does provide far better deals and support at least in this country compared to their Chinese counterparts.
