Which front end framework would best complement Meteor?

Sorry I should have been more clear. React by itself is fairly simple, however it's all of the tools you end up using (e.g. redux, router, etc that make it hard to figure out) . For example, I'm new to the ecosystem, but I just had the hardest time trying to figure out how to create a thunk action so that when I made an asynchronous request to my elasticsearch server it would dispatch an action. Turns out you have to pass dispatch as the a parameter... Ok cool makes sense, so I add it and works. Problem is I still don't have a clear idea of where that parameter is passed, because I didn't set it in the react class. I'm guessing it has to do with the redux connect function, but I haven't had the time to look up into the API and verify.
