Barnes if you're a meat hunter and also if you want to go for bigger game. Barnes will penetrate and then some. I haven't used the accubond, but have used the scirocco in my 300 RUM and 7 SAUM and it is one heck of a bullet if your gun likes them. I had a client shoot a 7'9" grizz with a 180 tsx this last fall and it went from shoulder to ham and exited. He used a 300 RUM pushing them at 3200. I would go with whichever shoots best and if both shoot the same, flip a coin you can't go wrong.
