React expects you to do your development on some flavor of Unix, and really doesn't have a sane plan for Windows, so you lose VS.NET and its huge productivity gains. And it needs tools upon tools upon tools to set up, whateverify, transpile and pack the files you write into something that can display in a browser. Again, this all seems to want to run from a Unix command line.
I want to edit some HTML and Javascript, then reload the browser and see my changes. Angular isn't perfect, but at least it lets me do my thing without adding a bunch of extra hoops.
