IMO Angular1 and React are so different in their approaches that it does not even make sense to compare them. If you want to base your application on a 'kind of' functional design with sane reasoning you should know what to use.
With Angular2 the discussion will be more interesting, but as far as I know Angular2 is not quite production ready.
Which is why we compare results, and not their philosophies and methodologies. It's like comparing CPUs from AMD and Intel, they have different architectures, but to understand real world performances, we compare results.
