After personal experience and reading a lot online I won't buy anything but the Samsung micro SD cards. I have SanDisk cards too, but none of them run the advertised speeds or can sustain the speeds. I found this out the hard way with my GoPro camera. It won't keep recording video if the speeds drop below 10mb/s so it shuts itself off. The only one to work was the Samsung. This may not be as a big of a deal on these phones, but it was enough to convince me. I have 3 64gb SanDisk cards and not of them benchmark the advertised speed.
this is the one I bought from Newegg, it was more expensive but worth it.
