Imagining solutions for imaginary problems
I think @camoloc is spot-on. I have multiples (fancy script and plain script/text on the back) and I have an earlier Gem (not a Junior but with a bar), and the tightness (clamping strength) of the bar and retaining clip are what I believe make the shaves feel slightly different. My "perceptual preference" is the Gem Junior Bar with the fancy script on the back -- I love the way it looks and I know that's a big part of it as well.
