It's difficult to say "It's always best to stick to the gauge it came with." Because what if someone loves playing in Standard C? Or even Drop B? Or perhaps they simply like a 9 instead of a 10 on the high e. It's okay to change string gauge, but I will say it would be a great idea to have your guitar looked at and the intonation checked after moving up. The action is something most people can adjust on their own.
