Initialize a vector array of strings

It is 2017, but this thread is top in my search engine, today the following methods are preferred (initializer lists)

std::vector<std::string> v = { "xyzzy", "plugh", "abracadabra" };
std::vector<std::string> v({ "xyzzy", "plugh", "abracadabra" });
std::vector<std::string> v{ "xyzzy", "plugh", "abracadabra" };
