My variable is shorter than Dave's, but is one better than the other?

I've just finished the 'Practice Basic Variables, Input & Output in JavaScript' workshop with Dave McFarland. His solution to step three of the challenge was as follows:

var completeName = firstName.toUpperCase() + ' ' + lastName.toUpperCase();

My solution was as follows:

var fullName = (firstName + ' ' + lastName).toUpperCase();

My question is: is one solution 'better' than the other? I feel like mine is more efficient, but could there be a scenario in which it might be better to use Dave's method?

Thank you in advance! :-)

In this case both solutions are equivalent, though Dave's more strictly addresses the objective. It would only make a practical difference if something other than a space were being concatenated with the capitalized names that you did not also want to be capitalized.
