AMD is in a really good position right now.
Intel still has the lead in low idle power which is good in laptops.
Ryzen lets different cores have different max frequencies so if your code is single threaded and your operating system isn't the newest that could be a reason to go Intel. Likewise if its single threaded and can take advantage of AVX-512 or the Intel Math Kernel Library.
But otherwise?
The BLAS & Lapack subset of the API of the Intel Math Kernel Library (MKL) is very well implemented in open source projects such as OpenBLAS and BLIS:
Both are well optimized for AMD CPUs.
