Which one is more suitable to use with meteor : angular 2 vs react ?
It’s really hard to answer questions like this. Everyone has their own preferences. So, try to see what you want achieve.
Then, try both and decide. Don’t listen to others 
The question is how fast would you like to go into production. Angular2 is still in alpha (even not beta) and API can be changed in any time. I don’t think that they will have stable release this year.
