Have tried Matsuzaka, Kobe, Hida, the best Australian, Luger, .... and many of the best of the world except Argentinian. My fav? Best is in Korea. Think best Japanese beef with similar marbling but not the fattiness. Stronger taste and firmer texture. Best in Korea is probably Park Dae Gam but Bamboo House might be more accessible for foreigners. Second for me is probably Sostanza in Florence. Third will be any of the best beefs in Japan.
