I don't see the os as a factor in choice of Fortran. Ifort and gfortran worked well for me, and I've heard cvf is ok. Fortran was not a factor in my decision to revert to 8.1 on the ultrasonic. I still use ifort and gfortran on win10 desktop.
In my case I am developing C++ wrappers for various FORTRAN 77 libraries (QUADPACK,SLICOT...) and OS does not really matter. What is more important is the right Compiler and Ifort is an appropriate tool for compilation and optimization. I was pleased to see AVX2 FMADD instructions emitted when ifort compiled FORTRAN 77 code.
