Have both. Use ceramic for larger cases...good stuff. Use the SS pins for smaller cases. Have to be very careful since the pins are so small and light that they adhere to the sides and top of the tumbler. Jury's out just yet. 
I hear there are a smaller ceramic media for smaller cases. That may be worth looking into.
What cases are you looking to clean?

Here's an article on the subject that you should find interesting.

Does anybody use B.B.,s as a medium, if so how does it work?  Thanks for your answer Hank45    

Response to luck88 regarding cases/calibers.
I shoot quite a spread of BP calibers from 32 cal. to 50 cal.

I recently bought into the stainless media and love it! Usually tumble an hour an everything comes out looking like new. I use dawn detergent and lemishine with excellent results

In a Thumbler’s Tumbler (slow speed model), I routinely use the large ceramic media for straight cases—45-70 and larger .45’s, 50-70, 45 Auto Rim, .45 Colt, 44 Mag and Special,  .41 Magnum. Cleans very well.  I can run about 100 cases for 4 hours and they come out clean, including the primer pockets. 

I tried the smaller ceramic media in the .35 Remington, .30-30 and .32 Special, but it just seemed to jam. Worked best if I cleaned about 50 cases at a time. Finally gave up on it.

A few weeks ago, I purchased some SS pins from Buffalo Arms. 

Tried it in the .45-70 and larger .45 cases as well as the .35 Remington, .30-30, and .32 Special.

It did an outstanding job. Primer pockets are clean and it even removed some “baked on” BP fouling.  Ran it for about 5 hours with some heavily soiled BP .45-70 and .45-90 cases. 

But the downside is that the pins are easy to lose.

Found that a 5 gallon plastic bag-type paint strainer (was less than US $2.00)  from the local paint supplier works very well to keep the brass and the pins from “migrating” all over.

Fit the bag over the Thumbler, dump the pins and the cases into the bag, then wash out the dirt and soap residue from the brass and pins with the garden hose.

As one poster said, the pins do sticks to the sides of the Thumbler’s rubber liner. When done, I run a magnetic parts pick-up stick to retrieve the dropped pins as my wheelchair has pneumatic tires.
