These kinds of questions are always best answered using a benchmark ;)

Um, no offense, but no they aren't. This sort of question is best answered by considering code readability, and maybe memory usage. The odds that this is going to be a performance bottleneck in any real application are slim to none. Don't be a slave to Benchmark.
