Lexar - up to 900 Mb/s read, up to 600 Mb/s write, does not advertise sustained write
Sandisk - Up to 880 Mb/s read, up to 650 Mb/s write, 210 Mb/s sustained write
Onn (Walmart rebranded) - Up to 800 Mb/s read, Up to 600 Mb/s write, does not advertise sustained write
Sandisk writes faster and is actually confident enough to advertise the sustained write speeds, Lexar claims to be 20 Mb/s faster in read but you can find a review on Amazon on the Sandisk card that the reviewer tested both and found the Lexar to be slower
edit: also the Nintendo branded ones don't advertise the speed on product pages but it's been reported they are - Reads at 880MB/s and Writes at 480MB/s, with its sustained write speeds peaking at 100MB
