The Samsung Pro U1 SD Memory card is a decent card from Samsung. It performs about the same as the Sandisk Extreme Plus except this card comes in a U1 variant. Samsung does have a U3 version of this card but it’s much more difficult to find. If you need a U3 Samsung card the Samsung Pro+ is the way to go as it is the best memory card from Samsung.
Samsung memory cards also have some compatibility issues with 4k or XVAC S video in Sony cameras. And since this card isn’t U3, it won’t be compatible with Sony’s advanced video codecs.
For casually shooting with any other brand like Fujifilm, Canon or Nikon, the Samsung Pro U1 card works great.
