There will sure be some algorithms where numba/cython would do 
better (especially if they cannot be easily vectorized), but 
that's not the point. The thing about numpy is that it provides a 
unified accepted interface (plus a reasonable set of reasonably 
fast tools and algorithms) for arrays and buffers for a multitude 
of scientific libraries (scipy, pytables, h5py, pandas, scikit-*, 
just to name a few), which then makes it much easier to use them 
together and write your own ones.
