Hey there Michael - The point is kinda moot, unless you have someone up the street who is selling both.
The SimpleOne is the Taiwan built model. The Quickbeams were built by Panasonic. There were some subtle tweaks throughout the model runs, some of which can be referenced via the Quickbeam page here - http://cyclofiend.com/rbw/quickbeam If you are looking for sidepulls (or centerpulls), then you are seeking the SimpleOne. All stock Quickbeams were canti-post framesets. For your size requirements, you are probably looking for the 56, though with your pbh, I'd lean towards the 58. As far as gearing, neither were specifically "single speeds", but rather derailleur-less designs. Specific gearing suggestions has a lot to do with your riding style. I tend to run a higher-than-most fixed ratio, but then stock gearing for the coastable setup, which was 40/32 with an 18T freewheel. There are stacked freewheel options, as well as stacked fixed sprocket setups, which give you two options per side. I'd just try the stock gearing for a while. You'll find it changes the way you ride - forces you to develop a few gearing options. Now... there is three basic threads of "interest and opinions", "blue sky wish list" and "hey, where'd the 'Beam go?" for the next run of 'Beam-Ones - Rivendell "SimpleBeam" - New Model - Call for the Seriously Interested *https://groups.google.com/forum/#!topic/rbw-owners-bunch/sKo8E4qO-jI* SimpleQuickOneBeam Project - Blue Sky Features - What would you like to see? *https://groups.google.com/forum/#!topic/rbw-owners-bunch/ZeaMJ7yLnUk* Why no more Quickbeam/ SimpleOne? (The thread which spurred the original conversation) *https://groups.google.com/forum/#!topic/rbw-owners-bunch/QhzO4CFyz1U* Hope that helps.
