My pcp doesn't have any suppression (1st gen Beeman QB), so it's pretty noisy. Got a couple complaints to the po-po from the neighbor earlier this year, so I can't backyard plink with it anymore.
My Marauder is a quiet enough that the neighbors don't even notice.
I mostly use the Daisy 901 out back since it's really quiet. The Hatsan springer 22 isn't very loud either, I just don't enjoy shooting it much.
I've heard those Hatsan's are finicky in regards to the way you hold them.
