the button ones will be ALOT faster and more stable to use once you set them up over the universal ones. I'm fairly sure the mounts for the spools on the 6R are 12mm.
With the universal ones (a la LP) it takes a bit more effort to lift the bike onto it. First you gotta get the pads on the swingarm, not the chain, then slide it back until you hit the spool mounts to make the lift points spread out enough to fit the back of the swingarm, then you can lift and hope one slide doesn't slip forward.
With the "L" style, you just position the spools in the "L" 's and lift. done.
