I have all three. I use the vibratory tumbler for almost all of my brass cleaning, definatley 100% of my pistol brass. It is WAY more efficient than wet tumbling, I fill, turn on, the sift the brass out and put it right into the press. I like the fact I can laod reliable ammo from brass that was dirty 30 minutes earlier.
SS WT sure does give give you some purdy brass, but it really is a pain in the ass. All that decapping first seems like energy wasted, then you gotta get all those damn pins out of the cases and flash holes (the cleaning solution makes them cling on for dear life), then you need to ensure everything is 100% dry before you even get them near a primer or powder. Meh, SS wet tumbling is good if your selling range brass but it's WAY too over rated for home loading. I guess it appeals to the OCD guys but I'd rather be out shooting.
I also have a large 10 liter heated ultrasonic tank, I use this for cleaning complete pistols, gun parts, carburators and other intricate doodads. It works well on brass too, but again I prefer my brass dry.
