IMHO-

**Bong - Top notch smoothness, no harsh throat afterwards. gets you the most baked...

**Bowl - Perfect for on the road or at work/school..(has to be thick glass). a tad more harsh than a bong

**Bubbler - too much trouble than its worth... tips over too easily, and i find its hard to take monster bong-like rips without charring my throat

**steam roller - ugh.... the harshest of the harsh..you cant puff it like a bowl...instead you have to revert to inhaling a fat ball of smoke strait down to your throat...

**VOLCANO - Pure ecstasy!!!! clear non sleepy yet still stoney high... no harshness (no smoke either) the cream of the crop IMO
