Yes, that's a good analogy, although the nm number by itself isn't the full version e.g for 28nm alone, TSMC had 28HP, 28HPL, 28HPM, 28HPC and 28HPC+ variants,

Yes, that's a good analogy, although the nm number by itself isn't the full version e.g for 28nm alone, TSMC had 28HP, 28HPL, 28HPM, 28HPC and 28HPC+ variants, of which only HPM and HPC (but not HPC+!) are at all compatible.
28HPC+ and 28HP have very different performance, even if they're both "28nm".
And if you really want to specify a process you also need to know the metal stack (lots of options there), Vt selection(s) (most processes have 2-5 options) & high-voltage device support option.
