I think yes. Flow requires less effort for project migration.
When in our project we decide to have the type system, Flow wins with the really great advantage you don't need to rewrite your project. In our case, we have the pretty large code base in pure js and fixing all ts warning costs too much for us.
BUT, personally, I think that TS is better(IDE support, bigger community, better typings, and is more flexible). And for new projects, I believe TS is a good decision.
And I agree that having this 2 standards is bad.
P.S. Also I want to mention that for me personally Flow community looks really weak.
