They've all got the same geometry, stiff frames and flexy handleposts. I remember someone on these boards saying they couldn't tell the steel and alloy frames apart in terms or ride quality; if that's true then there's no point in the extra weight of the steel frame. . . but I tend to think that there ought to be a difference. I think the Mu style frame is mainly an aesthetic choice though there's no chainstay so getting the chain off is easier, at least for the IGH type.
I'm guessing it'll be unquantifiable things that'll influence your perception of which 'ride better', i.e. the tyres might be over/underinflated, the hubs overtightend, or you might not quite have the ideal seat post height adjustment, and you'll interpret that as an innate superiority/inferiority of the bike's design. Really I think it comes down to what type of gearing you want, what tyres you want, what style of frame you think looks nicer and whether or not steel is worth the weight penalty.
