Sony is my go-to brand for SD cards. I do a lot of (semi-professional) photography, and I've never had a card fail, unlike SanDisk and Lexar. Small sample set, so not an indictment of the others.
I tested the performance both in-camera and on my PC (make sure you have a UHS-II capable reader). Easy to measure the performance on my PC, and I was very pleased to see both read and write speeds very close to the listed speeds. No way to directly measure I/O performance in the camera, but buffer flush operations were very quick.
Install the SD card monitoring software. Flash memory cells do wear out, and getting an early warning that your card is wearing out is pretty important.
