Vaginal physically feels better, but anal is a bigger mind trip. And since anal is experienced less frequently I enjoy it more when it happens. As fore your question, for all out feeling, I would have to say that neither compares to a really great blow job. The sensations that a woman can create with her mouth is out if this world. I know that is not your question, but you asked which is best.
