Try not to get anything that is chinese, it usually made of crap quality and will break down quickly, except mya's
for a easy draw theys no easier then egyptian hookahs theyfore KM's Mz's will be a good choice
For durability i would suggest a syrian or mya
And for easy of clean in my experiance nothing cleans easier then a mya
But Km's/mya's/ syrian's are all high quality hookahs, and will all smoke really well if set up right
And the difference in them are minimal, but i would suggest getting a hookah that looks good to you and post a link and someone will tell you how it is.
Try not buying from smoke shops if you dont really know much bout the hookah as it might be a piece of crap, try ordering online and post a link of it here
As for muti-hose hookahs they are more hassle then worth so your better of getting a single hose and passing it round.
And for the a great smoking experience getting a washable pipe and mayb a phunnel/vortex
Il get you started on some good hookahs
