Nachod :
Note: Both are Micro Sd's sorry for the typo
Pro is faster.. I would use the pro for like gopro 4k video or 1080 recording and the other for your phone (like photos and some video) if that make sense.
I use sandisk extreme plus class 10 for my gopro and regular class 4 sandisk for my phone.
If you need to record in high quality video you need faster card and to upload to the computer it helps as well.
