Personally, I would not, because. decided everything for myself. But it is always possible and necessary to compare, and this is where the truth lies. A tool like Component Kit, the progenitor of React Native, once showed us what high performance is like compared to regular native tools. But that was just a Facebook case that spawned both of these technologies. Most of the others are still unoptimized, and it's hard to say how they will behave in the case of your application.
If cross-platform frameworks have lower performance than native languages, how noticeable will this be to the user?
As I said above, for the average user it will be rather imperceptible. But this is only if the developer was extremely careful, knew what he was doing, did it not for the first time, and was familiar with most of the problems of the technology that he was using. But in the general mass, it must be admitted, given the low threshold for entering the technology for developers, such applications will be very visually different due to the lack of smooth animations, visual components that are not native to the platform, and also have poor layout on some rare devices.
