After some research and testing both cards in my laptop's SD card slot using Crystal DiskMark, I found the large block read/write speeds for both cards was comparable but the Sandisk had good small block read/write speeds while the Patriot's small block speeds sucked big time. Linux and related OS tend to do a lot of small block read/writes so that a good result in the small block tests is pretty much needed.

This, pretty much. Stick to SanDisk and Samsung for microSD. Doesn't really matter what class. I actually have Samsung Class 6 cards that beat other Class 10 (even SanDisk) in terms of small block read/write.
And beware of ebay or Amazon Marketplace fakes.
