On terms of sheer detail, the Dragon Pennsy comes out the victor, but the foremast is way large out of scale, so study of pics of the real thing will reveal this and guide you in modification/scratch building of the correct scale part. The PE fret is awesome. Mine has a couple of sink marks in annoying places on the one piece hull/deck molding, but not bad though. I have no photos of it yet.
The Indy has far fewer parts, but is an absolute joy to build. No PE is included, and the mainmast is rather simplified. Again, studying photos you can add the pieces to the mainmast and make it look pretty good, mostly all it takes is some stretched sprue cross braces. I did mine OOB other than that.
I think you would like them both.
