Here are three listings on Amazon:
Western Digital 20TB WD Red Pro NAS Internal Hard Drive HDD - WD201KFGX $419
Western Digital 20TB WD Gold Enterprise Class SATA - WD201KRYZ $525
WD Ultrastar DC HC560 WUH722020ALE6L4 20 TB Hard Drive $377

As far as I can see, all three are the same drive just with different firmware.
Seems to be some slight differences in noise levels and power consumption.

My use case is a 16-bay Supermicro server using an LSI RAID controller.
Currently using 12x 4TB SAS drives that run about 10w each. RAID6, Server 2022.
Thinking of using 4x 20TB drives to do the same with fewer slots and much less power, heat, and noise

So, my question is, has anyone found any reason to choose one type of these drives over the others?

The obvious thing would be to pick the cheap one, unless there is a good reason to choose the others.
I doubt I could justify the Gold, but there might be a case for going with the Red Pro.

Thoughts?

Oof, they just dropped the Red Pro 20TB to $329 for black Friday....
That's a pretty good deal.
