I don't know why people have such a hard time with Sankes. They are easy to clean and I never have to scrub. An overnight oxy soak and Viola! Taps being more expensive is true, but after the initial purchase of a few (a few more free if you know a cool beer salesman) they are far less work (not considering your arm can't reach in them, but you can't with a carboy either). Sanke taps go on one way and have way way way fewer parts to worry about sanitizing.
Kegs are a "to each their own" type of deal, but how many friends with kegerators that don't brew can you easily take a keg of your stuff to and instantly put it on tap? If you don't fear the smaller hole, or the more expensive tap connections (I have 3 now, and only need 2. True they get more expensive if you have more kegs on tap), then they are superior in my mind. If those are your only two worries... then remember all the o-rings (5), posts (2), poppet valves (2), smaller diameter dip tube (1 and hard to clean since you can't get your "arm" in there or even a brush), and the biggest for me... don't seal and set without a shot of pressure 9/10 times.
I ferment in a Sanke under pressure and never have to do anything to have a sealed and set keg. This is with low pressure build up, not so when I was using Cornies. Some people have no problem with good seals, but all the extra places they can leak other than just the 1 o-ring + the fact that they are the commericial standard makes them more attractive to me. Just my other $.02.
