I have been advised to use Samsung cards in the Note 3. I had a SanDisk card in my OG Droid and it died on me. The Note 3 manual says:
Some memory cards may not be fully compatible with the device. Using an
incompatible card may damage the device or the memory card, or corrupt the data
stored in it.
At least by using a Samsung card, if it does die on you then they will have a harder time explaining themselves to you. I bought the Samsung one. But always periodically backup up vital data to the PC in case of card failure
