The Intel is about 35 dollars cheaper and the same storage space. Is the WD one noticeably faster for the extra 35 dollars? Will be using the drive to boot my OS and a few games.
Intel SSD 660p series uses the cheaper 64-layer QLC (quad-level cell) 3D NAND but has better performance in general use.
The WD Black uses the more expensive TLC NAND.
Would it be worth spending the extra 35 dollars for the WD?
I recently went with a couple of Intel 660p's. If you were willing to spend the extra $35 on the WD Black for some reason, I'd recommend that you just get the 1TB Intel 660p instead...
Choose the WD Black if you are doing lots of burst writing to the drive: database work, multi gigabyte sized file copies, etc. Otherwise the 660p is a better value. For boot and gaming storage it's the cheaper drive every time.
