@Drb477 I too share your like of white dial pieces. I am with you on that. Of the 2 you are torn between, I would take the EXP-II, it is a very well resolved design which takes much of the best of the originals but in a modern case. I am a massive SMP fan and indeed have owned many, many earlier versions (10+) but I am not sure the current white dial model is best served by the black bezel. The Great White did it better for me.
I note you have the rarely seen black dial 1957 Broad Arrow Speedy as part of your collection, I actually have the reverse dial version of that. It is actually 4 different silver finishes rather than flat white but the overall effect looks white at first glance. Anyhoo here are a few pics below of my white ( or near white) pieces for your pondering, the last a curve ball I just happen to have on today:
