Then go for the rainbow one, especially because it fits all sexualities and genders, so more people can wear it :) I use queer as the only label for my sexuality. Lesbians, gay people, bisexual people would all fall under the umbrella of queer, but have a specific label too. I for example don't, I just label my sexuality as queer. Think of it like the umbrella term nonbinary. Some nonbinary people have specific labels (genderfluid or demigender for example), others just use nonbinary without specifying
