From a technical, "craft" standpoint, Hardy, McDowell, and Lloyd all did a better job. Unfortunately, Hardy's script was shit, McDowell's character was uninteresting, and Lloyd had certain preconceptions hanging over his head that made it hard for people to take him seriously.
I actually count Kruge as my favorite movie villain. I thought McDowell played a "sympathetic" bad guy well and Hardy and Bana made the best of very thin characters.
But if I'm showing a Trek film to people who don't know Trek, I'm going with The Wrath of Khan
