I've been running a 500GB WD NVMe SSD in my desktop for a couple of months now, and it seems to be working fine. Last week I installed a 512GB WD SN520 PCIe 3.0 X 2 NVMe SSD in my laptop because the original Liteon SSD failed. This SSD also seems to be working fine. I think the Samsung SSD's are the best out there, and are probably worth paying a little more. I just like trying different stuff now and then and so far have no regrets with the WD SSD's.
