Sandisk it always the best value for me

Though you will pay a little more because of the name, hands down the quality is there and you can rely on the storage to do what it is designed to do. I've been buying Sandisk Memory Cards for years and have never had to replace one. Extreme Pro is at the top end of speeds so reading and writing isn't an issue. Just be sure, if you are going to be using your card in multiple devices, to buy the card that will meet the speeds of the highest device you own. This will allow you to use it in any of them as it can easily handle slower speeds.
