Personally not a huge fan of two-way binding. As someone who has come from the C#/XAML world (where two-way binding can be abused), I found the pure-functional component strategy for React and similar frameworks to be far, far simpler.

Now, I do agree that it can lead to a bit of boilerplate, but this extra verbosity helps keep a simple mental model for us to reason about. Two-way binding can get very complex when you can have weird cyclical state changes.
