Sandisk, Lexar, Prograde. Depends on the application.
My raspberry pi doesn't do many disk operations so the speed isn't critical and 90 MB/s is plenty. My digital camera, on the other hand, has dual SD card slots, and can record uncompressed(!) 10 bit 4k video @ 60fps but needs 2 x 400 MB/s continuous write, which is... a pretty specific need. And cost accordingly.
