Since picking up my Chosera 1K, I've not had an itch to try any other bevel setter. My DMT's never get used save for lapping now. Occasionally I'll pull out the DMT 325 to get a restored wedge bevel started as it saves a bit of time before going to the chosera, but other than that I use the chosera for everything and then jump to the coticule with dilucot.

I have no desire to set bevels on a coticule (though it can be done) and having a dedicated bevel setter like the chosera just makes things so much easier.
