Both cards are good cards and are mostly the same. Both have the same cooler, base/boost clocks and chance of overclock.
The SC2 has 9 more sensors and you can set the speed of each fan independently. The SC Black has just the standard nvidia sensor in the gpu and both fans always run at the same speed (that you can change with PrecisionXOC).
If I were to buy a new one I would buy the SC2 just because I prefer to have the 9 extra sensors (the different fan speeds are not important to me).
From my perspective, the only reason I see for buying the SC Black instead is because MSI Afterburner knows nothing of extra sensors or asynchronous fans, so it doesn't work well with ICX cards. If you are a fan of Afterburner or do not like PrecisionXOC for whatever reason, get the SC Black.
In the end, which card model you buy is completely up to you, since you are the only one that knows if you like the extra features or not and they are not going to make a major difference in performance. You can be confident that both cards are a good buy.
