[m&p45acp10+1]

Personaly I do not care about spots, or having my brass super duper shiney. As long as it is clean. I use the sonic cleaner due to a few reasons.

1 Yes it is much quiter.
2 It is much cleaner to use in the house. (Live in an apartment so no shed, or garage.)
3 I have major allergies, and the dust makes me clogged up, and sneezy for a day or two.

Note I do still use my vibratory tumbler on super dirty range brass. I run an extesion cord outside and run the brass for a bit till all of the crudd comes off.
