im a Flow fan, but Flow's IDE support is pretty bad. WebStorm only souped it up recently, and aside for that, outside of Nucleide (and even there!) its pretty awkward/slow/clunky and in many cases downright buggy.
TypeScript's type system is very bleh, but its IDE integration IS pretty good across many editors (not just VSCode)
