I have owned both, and Darumas give you 75% of benefit of much more expensive Aurios MIB for much cheaper price. Galen Carol is a good source for these. Also easier to set-up, although new MIBs allow the single bearing on top (for extra cost) which I've heard makes set-up a bit easier.
I like these under CDP but keep in mind you must have cables that don't exert much push/pull force or bearings will be offset and not effective. This is my current situation so I am using large brass Mapleshade cones currently. I am keeping a couple sets of Darumas handy in case future cable change allows their use again.
