I have spent more than fifteen years in software: C# and .NET on the server, Angular and React on the client, and a great deal of plain HTML, CSS and JavaScript underneath both. So this is not a tribal answer.
For a business website, the kind that describes what you do and collects enquiries, the framework question is usually the wrong one to start with.
What each one is good at
Angular is a full framework with opinions about everything: routing, forms, dependency injection, HTTP. That structure pays off on a large application maintained by a team over years: enterprise dashboards, internal tools, anything with heavy forms and complex state. Its strictness is the point.
React is a view library with an enormous ecosystem. It is more flexible and lighter to start, and it is excellent where the interface is properly interactive: configurators, dashboards, anything with a lot of client-side state. The cost is that you assemble your own stack, and those choices are yours to maintain.
When you need neither
A six-page site for a clinic, a manufacturer or a local service business has almost no client-side state. Every framework you add to it ships JavaScript that must be downloaded, parsed and executed on a mid-range phone before anything appears. You are paying a performance tax for machinery the site never uses.
- Brochure and service sites, blogs and local business sites: hand-written HTML and CSS, with JavaScript only where it earns its place.
- Sites with real interactive sections: a static base with an island of React where the interaction lives.
- Applications behind a login, heavy forms, real-time data: this is where Angular or React pays for itself.
The question worth asking instead
Not "which framework", but "what is the least this page can ship and still do its job?" That question produces fast sites regardless of which answer you arrive at, and it is the question a developer who has had to maintain all three tends to ask first.
