Do you need more computers? I am asking only in case if you didn't, one more powerful is better than multiple weaker.
For 32GB modules, only the Corsair is currently available, and the correct bins are 3000 CL15 or 3200 CL16 (they're probably the same with the latter of slightly better binning).
In early 2020 there should be more options, but right now just this.
