Most (all?) Crucial and some Intel ones have some power-loss protection using capacitors, most others do not. That alone is IMO a good enough reason to ignore other vendors' SSDs.
On Samsung specifically, some recent anecdata to ignore: I took my old 840 EVO out of the parts box and used it for a temporary deployment recently, with pre-deployment testing including using 'Samsung Magician' in a Windows environment and then under Linux running smartctl's long test. The drive passed all tests and then was fully written over, so no chance of stale data triggering the known issue. It errored in use on day 34 and again the next morning, at which point a replacement was procured -- but the Samsung still passes all tests I can throw at it ...
