I have both the vibratory and the Thumlers, and after using both, IMO the vibratory is still the winner.
This is just my experience with the unit, YMMV.
The Thumlers with stainless pin media, water, soap, and Lemishine, does get brass clean, but, IMO is a big hasle to use. After the brass is cleaned, you have to dump the water/soapy mixture into the sink, rinse well, without losing any of the brass or steel pins, clean up the soapy mess you just made, and then spend more time drying the brass. Then you have to do all that over again, if you have more than 2 lbs. of brass to clean.
The Thumlers has a 15 lb. capacity, unless you get the larger tumbler, (40 lb. capacity) which is almost $800.00. By the time you get the steel pins and water in the unit, this leaves room for approximately 2 lbs of brass, which works out to be:
.45 160-180 pieces
.40 210-220 piece
9mm-230 pieces
.223 150-180 pieces
This might be okay, if you are using a single stage press, working up a new load, or just loading a few rifle rounds, but if you have a progressive press, you might just find that you are spending more time cleaning brass, cleaning up the mess, and drying brass, than you do loading.
Here is a link to a vid, that shows use and clean-up.

The vibratory type also has many drawbacks, dust, bits of media on the floor and in the press, etc. etc., but for speed and price, you still can't beat it. I can easily clean 1000 9mm cases at a time in one vibratory tumbler, and have clean brass in an hour. I add 1000 cases to my vib tumbler, and let it run for an hour, remove the first 1000, add 1k more, and let them run while I am loading the first batch. I can easily load 4k - 5k in an afternoon/evening like this. With the stainless tumbler, I'll be lucky if I get a 1000.
