In my humble opinion, it depends on a couple of things. First one, which strings you're playing. For example, I liked The Duke with Chromes 40-90, but it's nothing special with well broken in Sunbeams. And it's of some importance too, which Split-P you call "standard".
Some people who know Fender Pure Vintage '63, say that The Duke sounds very similar to PV63, but not exactly the same. They say, it's got a little bit more mids.
I'd say, it's jolly well worth a try as those don't cost an arm and a leg.
