Better is a very subjective question; however, style 1 will run faster since it won't look for variable interpolation. Personally I always use style 1 unless I specifically need variable interpolation or one of the special characters such as a newline. Also when doing HTML the double quotes fit nicely in the the single quote paradigm. On the other hand when I do SQL queries, I often allow interpolation just because it is more readable and because I usually use single quotes to wrap strings in my queries.
