Always a better way

There's always a better way in perl. Like methods to string unwanted whitespace from the beginning or end of strings. Here are two examples – both using 2 lines of code. Which do you find more readable/maintainable?

$str =~ s/^\s+//;
$str =~ s/\s+$//;

or

use String::Util 'trim';

$str = trim($str);
