Thanks for your comments. They are what I was looking for.

I have a President (Red, Fine) and some 1911 Large Sizes. The President is a touch longer capped, but it looks like it is the same cap removed.
IMHO:
The bands (mine are gold on both pens) appear a little wider on the Sailor at the end pieces but about the same elsewhere. There's also a medal band at the end of the section ont he Platinum.
Both nibs are excellent, but I find the Sailor's own nibs to be just a touch flexier (21k) than the Platinum's (18k) nib. Otherwise both are smooth.
I don't know for sure (perhaps someone else does), but I think the Platinum nib is German-made and hence somewhat stiffer and a little wider in the line. That is speculation on my part, but I do find the Platinum to be stiffer and a touch wider (comparing Sailor's Fine to the President's fine.)
My personal choice (and I think it is truly a matter of taste) favors the feel of the Sailor. I own several of those and only one Platinum. However, the President is an outstanding pen and I love to write with it.
For what it's worth....
