I have MicroMatic's offering with the large handwheel. Whatever brand you get, having the large knurled adjustment wheel that doesn't require a screwdriver is always nice, especially if you use it for different things like rapid force carb, or bottling, where you are tweaking the pressure. Other than that they are essentially the same and very simple devices.
If you are going to set it as the main regulator on a kegerator and never move it from your normal serving pressure, any of them will work.
