I have to say i've smoked roor, illadeph, aqualab and many more but my favourite so far is my cheap cyclone, it's a knock off hurricane, 38cm tall, came with three sized pieces, the inline ashcatcher is awesome, i put a carball inbetween the piece and the catcher and although i change my water daily, i could get away with weekly easily it stays that clean. On the subject, it's not too hard to clean, the gong joins are solid without getting stuck and i swear you could split someone's skull with this thing. The two things i'm most impressed with though are the three 'air jets' along the height of the bong that create the cyclone effect by injecting streams of air in opposing directions as you pull, i thought it would be a gimmick but you can not only watch the smoke swirl as you pull but after about a dozen bowls you get a visible build up of tar on the glass next to the jets, this is with an ashcather and carbon filter remember, so it really does help to push all the heavy particles outwards which leads to the best thing about this piece-it's smoke. You can load up the party piece, easily a triple bowl if not more and if your a decent smoker, near knock yourself out snapping it down in one regardless of if you pull slow or drag at it so you go red, the smoke is always as smooth, never get any splash back even if the load blocks and dumps and you don't end up with a lungfull of hack from the excess water moisture in your smoke, it's like breathing out tasty air really! Even with a lungful of flu i can rip bowl after bowl and not die. If you ever get a chance to try one out, even the cheap cyclone version do it, i'm already saving to get the real deal, they play soccer with those things on tiles!
