yes that is one of the main reason. Another reason is because I'm super paranoid about SD cards going out on me and I'm hoping that "the best" line up will atleast have better quality than the average one and will last longer.
I don't also trust cheap prices, better buy the exact price than buying a cheap one that could cost you more.
Stay away from sandisk sdcard with red/grey color if you want to use on samsung devices. I had two 32gb sandisk microsd card failed on my previous galaxy s3, both were sold by Amazon directly. Both cards failed when I was downloading several files simultaneously for half an hour. Maybe they are good for light use, not for intensive writing.
You can google about the issue of sandisk sdcard with samsung phones.
