I prefer the finger perc myself.... I find it a tastier and tighter hit (less air filling my poor irritated bronchs to acquire the same amount of product intake). It was great for vapebonging with my Solo, dabbing with my skillet, and for kief combustion. Smoothness blew me away with the addition of a carbon attachment. I'm 'very' pleased with both purchases wise, however see myself using the hand bub more than not. EDIT to add: Both pieces are definitely of cheaper quality with the non symmetrical fingers and slits, but they do stack quite well and moisten/hydrate my intake great at a 1/4" max over the top slit.
