I haven't heard of this issue, at least not on the Raspberry Pi forums I've frequented. Granted, I'm not a heavy RPi user, but I do have one and have spent some time on forums for information and hadn't run across this. Most discussions I recall have centered around the longevity of SD cards, given that they're limited to a certain number of read/write cycles. Of course, it could just be that I'm not on the forum often enough to hear of corruption issues.
For my own Raspberry Pi, I've used Transcend and Kingston SD cards. The Transcend has more time on it than the Kingston. And the Transcend has probably put up with more "abuse." Since that was the first card I used, I spent more time with it installing, re-installing and whatnot to get it up and running. And, there were times when I had to shut down improperly (by disconnecting the power rather than going through the shutdown procedure) and that hasn't seemed to affect it. And, I would think, if an SD card were to suffer corruption, that would be the time most likely for it to happen.
It could be, as TWF and DK have suggested, all in the quality of the media, rather than the type of media. Or, possibly, the quality of the RPi board being used, since, as I recall, they are available from different manufacturers. Or maybe I've been lucky or just haven't used the Pi frequently enough to begin to see issues.
