Being an engineer, newer flash cards have a way of randomizing the flash write. Flash memory has a finite number of writes that can be done, around 100,000. Older cards without the newer write algorithms will fail sooner. Depending on how one erases the cards can affect the number of writes. I tend to just reformat the card. Just deleting files probably leaves the file system location in memory constant, and the first failures will probably be related to file system blocks. I'm not sure the difference with the Canon cameras whether the erase all is worse than the reformat, but if the card uses the randomization, in theory, reformatting the card to erase all files may give better life since the file system blocks will also get randomized. It is conceivable that if the file system blocks remain constant, then every photo taken or deleted will subtract from the 100,000 write lifetime. but that is just a theory on my part.
