To answer the question "what's best". My vote is the Buon Vino Super Jet. I have used this model for about three years now. Designed for filtering wine and works great for beer. Self priming pump makes it quick and easy to use. Minimal beer loss.
I like using this filter on my light colored beer - Belgian Golden Strong and Belgian Triple.
I keg most of my beer. To my palate I can taste quite a difference in the 1st, 6th and 12th glass of beer coming out of my kegs. Despite using Supermass HB and Biofine Clear, the bottom of the keg always had significant residue. The dip tube picks up some of this residue and taints the flavor in my beer. Others may not notice but I certainly can tell. With filtering there is only a very thin, paint like residue on the bottom. The beer is considerable more homogenous in flavor from start to finish. The things we do in search of perfection.....
