I like the sherlock bubble style, but I've only smoked out of a hammer once. I've owned 2 single chamber sherlock style bubblers and a double chamber and was extremely happy with the way all 3 of them hit, so yeah i'd go sherlock fo-sho
I've never owned a sherlock myself. My hammer that I owned hit really hard, but most sherlocks have hit harder. I'd go with a lock then if you're dissapointed, get the hammer later!
i wouldnt limit myself to one or the other. i would go in see what looks the best for your price range n choose that one. but if u want my opinion on what looks better id have to say a sherlock, but i still love my hammer
