Since no-one has replyed I thought I'd drop in my .02 just for your consideration. I have a number of cutters and none of them cut perfectly all the time. I agree that if a ceramic was somehow sharper than the others, then it might be better. It seems that the key to a good cut is sharpness rather than design.
I like to use a straight razor. In the old days the cigar smoking barbers used their straight razor. You fold it like if you were going to close it, then position the cigar cap under the blade at just the perfect depth. Slowly roll the cigar as you gently close the blade down on it.
This might sound a little tricky but is very easy and yields perfect results every time. Be sure to use every safety precaution and don't leave it where a child might find it. Don't forget to hone & strop the razor after using it!
