Class 4 have the fastest random 4k read speeds (afaik, class 6 MAY be faster), this makes a ton of difference when running apps off the card. I would suggest leaving the apps on the internal storage unless you run out of space.
+1 Class 4 or higher is the only ways to go. Anything under 4 should never be used with a phone or camera IMO. 6 is "faster" but not a big enough difference that you'll be able to see if you come from a 4. Go from a class 4 to a 10 and youll see a bit of a difference.
