Micro SD card for GOPRO
Bought 2 X Lexar Micro SD Card (model number AMSDC-232) online but the seller ended up sending 2 X SanDisk Extreme microSDHC (SDSDQXL-032G) and said Lexar sku has been discontinued and Sandisk is a better card in comparison.
My question is, Lexar sku is 600X (90MB read (cant find write speed) and SanDisk sku is 300X (45mb write 45mb write) How is that a better card?
FYI: I am going to shoot some 4K gorpo video with it.

Look up real world read/write tests, they aren't always what the manufacturer specifies. On that note I don't have an answer to which is a better card.

Write speeds vary wildly with sd cards, especially cheaper ones. The read speed is only achieved (and this is real world as I've some 600x SD cards) if you have a USB3 card reader and a USB3 port. Otherwise, you're never going to see those speeds in real life. Write speeds can be one number, but factors like camera buffer can affect real life performance.
If you're shooting 4k video, try and find the fastest writing cards. According to Lexar's website, their 600x write minimum 90MB/s.
What does 100x, 200x, 400x, and 600x (1x=150KB/s) performance mean? | Lexar
