I used to buy SanDisk Ultra (if I didn't need speed), Samsung Pro+ (if I did), or SanDisk Industrial (if I needed more reliability... not sure how big a difference it makes but I've never had one fail). But since Raspberry Pi launched their own microSD cards, I've been buying them. They haven't failed me yet and are pretty fast.
