Unpopular answer, but it's what we use here: Angular SPA front end + .NET backend The "best" is what you can get the best product done the most efficiently, and what you're able to hire for. If a niche new thing comes out that might be 1% faster in synthetic tests, but you'd have to spend 4 months learning it as well as what you know now and there are no people near you to hire, it's not really the "best" for you.
