I use 8 bottling buckets for my fermenters and love not siphoning. Siphoning is not a huge deal, but, it is one more thing that can go wrong. Also, in my experience, 100% of the autosiphons I have ever had got "micro cracks" in the plastic in a relatively short amt. of time and that concerns me as far as sanitation is concerned. I still transfer from my primary bottling bucket to another bottling bucket if I am adding priming sugar and bottling. If not, then I just transfer straight to the keg. I also find buckets by far the simplest type of fermenter to clean.
