New addition
The Praktisix II (center) is the best of both worlds: it has the simpler, less troublesome frame spacing system of the original Praktisix, along with its slightly more compact packaging (they don't have the big knobs sticking out the bottom like the Pentacon) ... plus the Pentacon's engraved (rather than printed-on) dials and click stops for the shutter speeds.
Other than those details, all 3 cameras are very similar in construction.
