I like Wet Tumble for the Flexibility and Reduced Lead Exposure. I can tumble a ton of pistol brass without pins, and that will get them clean enough in my opinion. Or you can get brass shiny clean if you want that.
Reduced lead exposure is definitely a positive! That would be handy when it’s below freezing outside here and I need to tumble indoors. I’m pretty sure I’ve tried tumbling without pins before when I first bought my wet tumbler.
I dry tumble in lizard cage media from the pet store long enough to remove case lube and that's it. It could be shinier but I don't want to deal with having to dry brass after wet tumbling.
