Agree with Slobber that the right one looks better. It is more common to use all-caps, but personally I find sentence-style capitalization more aesthetically appealing. Plus it's easier to fit more lowercase letters in a smaller space.
This is the most useful thread I have ever encountered! Definitely useful for a newbie like me who is attempting to try translating and editting (something simple though)!
Thanks to all those who contributed, definitely checking this up for more updates and tips!
