If you want the Micron, go with the Micron. It's a much better deal (particularly if you can get it for $255) and your concerns aren't worth worrying about IMO.
With that being said, you can never go wrong with a Samsung. Class-leading speed and reliability. I bought one of these when they were bundling a free copy of Far Cry 5 but will end up running two of the Microns because of the better $/GB.
