In order to ask your teacher which phrase is better, more natural or more native, you can ask:
Which one is the most natural? - Natural in this sense means the most appropriate to the situation.
Which phrase is best? - Best means the better one or the most fitting.
You can also ask your teacher, which one would you choose?
Or you can describe a particular situation and say which phrases would fit to that situation.
You can ask if it will work in daily conversation or in a formal setting.
I hope that helps!
