A CBOB is a CBOB. You get what DW gives you,the same as everyone else.
Fusion allows you to have a more input. They will build to your specs,but of course you pay more for that.
If a CBOB suits you fine,then go for it. If you want different sights or different parts or a different finish,I suppose Fusion is the way to go. They even have a railed Commander model if that's your thing.
