I love static typing, but prefer flowtype for js project. I used Typescript during the initial days while developing Angular 1 apps. Things might have improved now, but transpiling to JS was slow then and had non standard module system. It may make sense to use it for Angular apps as Angular 2 and related projects are written in it. but, for me, it always felt as another language farther away from JS. Once started using Babel + Webpack, I couldn't think about leaving the flexibility and standard compliance to Typescript (mostly react apps). Also, gave Nuclide and Flowtype a second chance this week, and they dramatically improved. As a drawback, there are tons of open issues on Flow tracker and seems more investment needed.

+1 for Flow. I've loved the fact that it's not a build step, so it was really easy to add Flow into my Babel+Browserify projects. I looked at Typescript before, but I didn't want to leave Browserify, and Typescript+Browserify did not look like it was a well-supported path. Also its strictness about nulls has saved me so many times and has forced me to make better APIs that carefully consider or prohibit them, instead of treating null as a boogeyman that I don't think about until it inevitably bites me.
