I would suggest that you read the reviews for both SD cards to find the answer to your question. As for pricing, currently on the link you posted the SanDisk card is ~$68, not $200. The Transcend card is $17 cheaper. I guess it comes down to whether or not you think it's worth $17 to get a product that has a better reputation for reliability. I usually buy SanDisk.
