Anapanasati vs Vipassana, what to follow?

I have a friend who recently did Mindfulness-Based Stress Reduction (MBSR) program as designed by Jon Kabat Zinn . I haven't done it myself but he explained to me that it is based on the Vipassana technique of awareness-based body scans. I have done S.N.Goenkya's ten days meditation courses but I **currently** follow Ajahn Brahmas meditation guide book Mindfulness Bliss and Beyond . When I told my friend who didn't know about Ajahn Brahma, he said 'his teacher said that calming the mind is a wrong technique of meditation'. Now when I look at it, S.N Goenka's Vipassana technique though good for healing the subconscious mind does not talk about reaching higher meditative absorption of Jhanas. Whereas Ajahn Brahm, in his book and in his youtube videos talk about reaching Nimmitas and Jhana through Anapanasati i.e. Breath Awareness Meditation. I want to ask; 1. Which is the right way to go? 2. What is the difference between Vipassana and Anapanasati **goals of attainment**? 3. Can I attain Nirvana without doing Vipassana but by just doing Anapanasati? 4. Is there a difference between Vipassana Jhana and Anapanasati Jhana?
