C# + .NET Core 3.x + Blazor server-side. This is modern PHP.

I've gone all-in on the Microsoft stack and have not regretted a single moment of this decision. If one can put aside the "big evil company ecosystem bad" argument for just a moment, I think it would be very difficult to say another ecosystem is superior in terms of actual time-to-market for your product.

I tried C# + .NET Core recently, and while the core language was excellent, I found the library ecosystem severely lacking compared to the PHP and JavaScript ecosystems.

And some of the best libraries which did exist were under commercial licenses! Which generally isn't an issue in other ecosystems.
