Who does mostly just pictures in single-shot mode, may well save some money with this card against the other. Who makes fast image sequence and / or videos, should take up a faster memory card and use it more as a backup.
Since I mostly only use single shots, I'm with the map, or rather very pleased with the space for the small price.
* Tested with Canon 7D RAW (L) + JPG (M); after 8 continuous shots the buffer was full and the slow writing speed of the card was noticeable. It went for a few seconds until all images written on the map.
