Question Which SSD is the best option here?

Probably little difference in actual use.

Both are gen 3 drives.

I think the Intel uses QLC and has DRAM

WD is dramless and uses TLC. WD is known to have tweaked its controllers pretty well for dramless operation.

I use an Intel 660p and a WD SN550. Satisfied with both.

You can look at benchmarks, but I'd be suspicious of making a big deal out of them.

Maybe warranty matters? Maybe different return privileges? The TBW probably is different, but I wouldn't get wound up about it.
