As someone who just watched Trigun dubbed for the forst time a year oslr so ago.... I would not call it a great dub. It wasn't awful by any stretch, but it doesn't hold up against something like Cowboy Bebop either. The truth is, there have always been, and there continues to be, really good dubs, but they have also always been few and far between. It takes more money than most are willing to invest to make them good, but there's always a few gems that are willing to pay up and make them work.
