Then you'd make a more sensible comparison like React versus something like SwiftUI which is constantly changing, constantly breaking, and still basically in beta mode for 10 years, yet it only runs on specific versions of Apple hardware and software. And usually it's so insufficient that you also build part of your app in UIKit/Cocoa in a completely different language.
React is far more stable to build with and far less experimental.
People who have never touched any UI tech until HTML/JS have no clue how good they have it, so they confuse universally hard things about UI tech with something that must be specific to JS, so they additionally assume it's so much better elsewhere.
You should try updating a nontrivial SwiftUI app you made for the iPhone 11 to work on the iPhone 16. Not only have your libraries changed (not just topical ones, but the Promise library you used is defunct and everything now uses Combine and 2021 Swift async features, so you have to migrate all of your async code), but the platform itself doesn't have APIs that you were using anymore. That's not even a class of problem you deal with on browser tech.
