Hi Peter, Riv describes the Platypus as "like an Appaloosa or Atlantis, but with a step through frame", and as you note the geometry is pretty close, so I thnk it's safe to say they would ride very similarly. The step through fame of the Platypus does make it a bit less suited for heavy loads so it's also safe to say the Atlantis is stouter and more suitable for heavy loads. Riv says the Platypus is good for loads under 30lbs.
I'm 5'11" with the same PBH and ride a 60cm Platypus. One reason I went with the Platypus (besides the look of the frame) is the ability to size up for a longer reach without worrying about stand over, knowing that I wanted to use a big sweptback bar.
