Hey there, g335!
I believe you should go with the WD Black because it's specifically designed for high-end rigs like the one you are building. Its purpose is to serve gamers' and creative pros' PC builds delivering high-performance while using your demanding applications.
You will be also satisfied with the capacities it has to offer, whereas the biggest WD Blue is only 1 TB.
The WD Black has a 5-year limited warranty, which definitely gives some peace of mind.
I strongly recommend checking the features of the WD Black here and see for yourself:

Here are the ones of the WD Blue as well if you want to compare:
